Bosch 11255VSR Bulldog

The tool we sell day in day out for our low voltage contractors is the Bosch 11255VSR Bulldog SDS rotary hammer.  The Bosch Bull Dog series has a long and reliable history.  It’s predecessor, the Bosch 11224VSR Bulldog was one of the top selling rotary hammers in the world.  When we look back at how many of these tools we have sold over the years and consider the very few repairs we have had to perform, we recommend this line with confidence.  Most of the concrete drilling you will encounter in your low voltage, structured wiring environment can easily be handled by the Bosch 11255VSR Bulldog.  The optimal drilling range for the tool is 3/16″ to 5/8″ which means it will drill these size holes all day long, it’s main use was built around these sizes.  It is rated to handle a 1″ solid bit and up to a 2-5/8″ thin wall core bit all though we have contractors who typically use 1-1/8″ bits for 1″ EMT  without any trouble.  You can turn off the rotation and use a chisel in the tool as well if you have the application.  As much of your work is done off ladders, the D handle is a nice feature to have.  If you are looking for longer SDS hammer drill bits, up to 38” and core bits up to 4-3/8″ to fit the Bosch 11255VSR Bulldog Rotary hammer, you can find them on line at ConstructionFastening.Net

UL Listed Plenum Red Cable Ties

UL Listed Plenum Red Cable TiesWhile no one likes paying more than they have to for something so thing like a cable tie, there are times when  UL listed red plenum cable ties approved for air handling spaces  are required.  I have seen some jobs where a vendor will supply plenum rated cable, and then sell the customer a standard cable tie rather than a UL listed or plenum cable tie.  Many times it is just an oversight and truth be known, many times it is overlooked by some inspectors.  We experienced an inspector who did not like a certain UL listed hanger and made our contractor jump through hoops to use them, but allowed standard cable ties.  UL listed cable ties used to be quite expensive and some offerings still are.  We offer a red UL listed plenum cable tie in both 8″ and 15″ lengths, with a 50# tensile strength that won’t break the bank.  Both sizes are made in the USA.  We have been selling these for years, they really are a quality tie.  FYI a 8″ cable tie will hold up to a 1-3/4″ bundle and a 15″ should handle up to a 4″ diameter bundle.  Plenum cable ties do not have to be red but it is a good way to differentiate between standard and plenum cable ties.  Our ties are packed in 100 count bags and are clearly marked as UL listed for use in air handling spaces.

Core Drill Bits

SDS Max (TE-Y) Core Drill Bit

SDS Max (TE-Y) Core Drill Bit

If you need to drill holes in concrete larger than 1-1/4″ or so, your best bet is a concrete core drill bit.  Core drill bits are available for SDS plus hammers, like the Bosch Bulldogs and the Hilti TE-15,  and your bigger SDS Max (Hilti calls them a TE-Y) and Spline core hammers.  Bits for the SDS plus hammers are available in sizes up to 4-3/8″ and the SDS Max (Hilti TE-Y) and Spline bits are available in sizes up to 6″ in diameter.  Most have a drill depth of up to 17″ or so.  Most rotary hammer drills show a rating for what size core bit would be at the upper end of the capacity for the drill.  I know some contractors that do exceed the recommend size, the key is to work slow and let the tool do the work.  As you exceed the recommended size on a core drill bit, you over power the drill and the tool will tend to clutch out more often.  Core drill bits on rotary hammers tend to blow out the concrete as they come through the work surface.  If that presents a problem, you may choose to drill a pilot bit through the wall or floor and start drilling from both ends.   You can find core drill bits for your SDS plus, SDS Max and Spline bits at ConstructionFastening.Net  Not sure what bit your rotary hammer uses?  Give us a call toll free at 1-877-212-2377.



Ramset Viper Ceiling Tools

The Ramset Viper ceiling tool has become the tool of choice for not only ceiling contractors but for electricians and limited voltage contractors or anyone who wants to suspend grid wire, pencil rod, jack chain or even 1/4″ rod from the ceiling.  To date, the Ramset Viper tool has had 3 major versions.  Below is a brief description of each model.

Ramset Viper Tools

Original Ramset Viper Tool.  The original Viper tool was of a metal body construction and had a manual advance system, similar to what you will find in the Powers Sniper Tool.  The tool was light weight and really bullet proof provided that you kept it clean.  There are still a fair number of these on the job, parts are all but gone.  The tool worked on either a fixed or telescopic extension pole.

Ramset Viper 3.  The Ramset Viper 3 tool added a few really nice features including automatic load advance and was designed to operate with less cleaning and maintenance.  Being a more complicated tool with more moving parts, repairs did increase a little but again really was a solid tool for day to day use.  The tool used the same extension pole system as the original Viper tool.  Parts are still readily available as the tool has only been out of production for a few years.

Ramset Viper 4.  The Ramset Viper 4 is the latest version of the Viper tool and has some significant changes.  Most note worthy on the tool is the fact that it uses a proprietary pole system for added safety.  You need to make contact with the ceiling and then push up on the outer trigger pole to actuate the tool.  There is a base pole portion that has the trigger sleeve, available in 3′, 6′ and 8′ sections and then you can add as many 3′ extensions as you choose.  The 6′ base is the most common all though I like the 3′ base and a 3′ extension, it just makes it easier to lock up in the gang box.  The tool shares some parts with the Viper 3, the piston, buffer, return pawls and the load indexer ball and springs.  So far other than a few pole issues in the first tools to hit the street, the tool has been very reliable.  The biggest problem we have seen is making sure everyone understands the pole tool is not interchangeable with other Ramset Viper Models.

You can find the new Ramset Viper 4 tool along with parts, pins & loads, pre tied ceiling wires, pole tools and more for all the Ramset line at ConstructionFastening.Net

Sleeves For Running Cables Through Walls

Many fire stop systems call for the use of a steel sleeve with fire putty or fire caulk to maintain the fire rating of the wall.  You have two basic choices.  Many are using pass through devices that come fully loaded with fire stop products, you simply install and run your cable.  While these really are nice and fool proof to use however…. adding twenty 2″ sleeves at close to $150 a piece can really change the look of your quote.  Many contractors opt for a piece of emt cut to about 12″ with Arlington hammer on bushings and fire caulk.  It is important to have a cut sheet from your fire putty or caulk manufacture showing a system using a steel sleeve and their product.  Keep a copy on file at the job and make sure you follow the recommended fill rate.

You can find pre cut EMT pipe from 1″ up to 4″, deburred and ready to install with Arlington EMT bushings at ConstructionFastening.Net.  You can really see the advantage of buying your EMT pre cut when you start using larger sleeves, especially in 4″ diameter.  4″ EMT is not readily available at you local big box store and if you need 2 sleeves, you buy a full stick, then you need to track down the bushings.  Then add to the frustration of cutting larger EMT.  Give our pre cut EMT a try and you will see why they are one of our top sellers.

Drywall Anchor Options

Everyone has their favorite method for fastening to drywall, here are few options for you to consider when you need to mount to the drywall.

Powers Wall Dog.  The Powers Wall Dog is a one piece drywall anchor that lends itself to fast light weight applications.  The anchor has a sharp point and very coarse threads and is designed as a one stop installation.  Simple drive it in and you are done.  Best used in lightweight static applications, perhaps on a sensor up and out of the way.

EZ Anchors.  ITW has been producing the EZ Ancor line for some time and there are several other manufactures producing a similar anchor.  The most common size is used with a #8 screw but you can get a light version that will take a #6 as well.  The anchor offers more holding power than the wall dog or a blue cone anchor.  Very easy to install, just screw in and add the screw.  Available in metal or nylon.




Strap Toggles.  Strap toggles offer a few advantages over the standard toggle bolt.  With the strap toggle, you drill a hole, insert the toggle and zip it up against the wall.  You are left with the toggle bar left in position.  Available in 3/16″ , 1/4″ and 3/8″ sizes.  Screws are sold separately.

The Savings.  Now here is where your savings come in.  Let’s assume you need to hang a couple of threaded rods to support a cable tray or just an access point.  First off, if you have been spanning the bar joist with a $20 piece of strut, adding a couple of clamps to pin it in place, then a couple of spring nuts, you have a cost of around $25 in parts.  Secondly, you have the labor of driving back and forth with your lift from one bar joist to the other to complete the fastening.  With the Sammy Express anchor, you will need 2 anchors, that’s it, to get to the same installation point.  You are in one spot, drilling two small holes and installing two anchors.  Install time probably about 2 minutes, it will take you longer to spot the location than set the anchors.  Total anchor cost under $8.  Yes the install tool will set you back a little, but you will never regret it.

The Sammy Express anchors have both UL and FM Listings.  Holding power is fairly impressive with an ultimate pullout of  over 1,000 so they can handle a wide range of applications in the data cable and security fields.  Click here for more data.  The Sammy Express anchor is available to handle 1/4″ for vertical mounting and 3/8″ for vertical, horizontal and swivel applications.  Find them on line at ConstructionFastening.Net
