If you are looking for a 2″ j hook with a beam clamp that will mount on a flange up to 1/2″ thick and be able to rotate a full 360 degrees, this is the j hook you are looking for.  This version has a standard UL listed hook mounted to pressed beam clamp similar to the Caddy BC200, Minerallac 600 or B Line BC442.   Some hangers have the beam clamp mounted to the back of the hook that limits you to running your cable with the beam or bar joist.   This  hook is mounted in such a way that it can be rotated 360 degrees if necessary.  Simply loosen the screw and turn.  Now you can run with the iron, at a right angle or even diagonally across a structure.

The real advantage this type of beam clamp used on this assembly versus a j hook with a hammer on beam clamp is that you can mount to any flange from 1/8″ to 1/2″.  With a hammer on beam clamp, you have to have at least an approximate idea of how thick the flange is.  Usually the clamps will be made in a size range of 1/8″ to 1/4″ flange, 5/16″ to 1/2″ flange and 9/16″ to 3/4″.  By far the most standard is the 1/8″ to 1/4″ but there is nothing more frustrating than trying to hammer on a j hook when the clamp is just a little to tight.  To be sure a j hook with hammer on clamp is still a very common part, we sell tons, but if you don’t know the flange size for use the standard beam clamp is a better bet.

If you are looking at j hook tree bade up of 2″ j hooks with a beam clamp, especially if it is a quad hanger, the pressed type beam clamp will offer more holding power and is a little more rigid than a j hook tree suspended by a hammer on clamp.

We are very excited to start offering J hook trees and components for cabling installs.  J Hook trees have been around from several manufactures for some time and they offer a nice option to cable tray while still offering a structured system.  The HPH J Hook Tree System uses the HPH series of j hooks which are UL listed, approved for use in air handling spaces, are TIA compliant and feature a built in closure. 


D-rings for cable management have been around for decades, and there isn’t much new in that world.  But one d ring that has been overlooked for cable management is the Arlington D Rings.  They are available in 2″ (#D-22), 3″ (#D-33) and 5″ (D-55) sizes.  The Arlington D ring has been out for years as well, so we want to give them a little push and address a couple of questions that we have had with them.

The first obvious difference is that they are made out of a smooth non conductive plastic material.  The size and shape are the same as the metal d rings that you may have been using for years in cable management, just different material and color.  The biggest objection I have heard from people is that they probably aren’t as strong as metal.  In some regards, maybe that is true, in other ways I would disagree but the real question is what are you using them for?  Unless you are using them as ladder rungs or pull handles, they are  far strong enough.  What is a d ring for cable management designed to do?  Manage cable right?   So you should have no trouble routing your cable and holding it in check with a nylon d ring.  If you are putting enough pressure on a nylon d ring to bend or distort it, you are likely putting too much pressure on your cable as well.  So there are my thoughts on the concern that metal d rings are stronger than nylon d rings.

Now here are a couple of things I like about the Arlington D rings.  One, they simply look better.  With a better fit and finish, your closets will just look that much better.  They simply look more modern than a raw cast piece of metal.  The black finish will blend in well with your racks and panels.  And a small detail but again one that ads to the over all look of the job is that you can install them with a standard black drywall screw that will blend right in.   So if you are looking for d-rings, we stock the D-22 2″ D-Ring, the D-33 3″ D-Ring and we we can bring in the 5″ as well if you have the need.

I have sold and serviced many powder actuated tools over the last 20 years including the Hilti DX350 and the clone versions of the tool from many different manufacturers.  They are just such a solid tool with many different uses.   Here are a few points to help you find a good deal on a good used Hilti DX350.  Don’t just accept the statement that the tool fires or works well.  I have seen tools advertised as working well when they were obviously missing parts in the photos. The tool will handle pins from 1/2″ to 2-1/2″ with washer making it a perfect choice for all around general contractors.  As it can be mounted to an extension, it is also a great choice for electricians, ceiling contractors and data comm/low voltage work.  The only use I don’t like the tool for is tasks that are prone to over driving the tool like  putting foam to concrete.  Check us out for pins and loads for the Hilti DX-350.

A Hilti DX350 tool should not just fire, it should fire solidly and advance one load each time you cycle the tool.  The most common thing a used tool may need is a piston or driver.  The piston or driver is what forces the pin into the concrete.  They are a wear part and so they chip up and can even break.  An aftermarket piston to fit the Hilti DX350 goes for around $30.  The driver is easy to replace.  If the tool isn’t advancing the load advance isn’t expensive, but it is a little more tricky to replace.   The little “C” clip that holds the front barrel together can get bent up from time to time.  Again this is a wear part, easy to replace and many of the tools have extra packed along with the tool.  Stay away from a tool that has cracks or breaks on barrel or fastener guide.  If the tool fires and advances but make just a “poof” sound, almost like a bad load, it is likely the return pawl that resets the piston that is warn.  Easy to replace but figure another $20 or so to fix.

When you are looking for a used Hilti DX350 tool you will find clone tools from Ramset, most notably the Cobra tool.  The Cobra is a great tool, but stay away from the Cobra Plus tools, many of the parts are not available.  As for prices, I have seen them all over the board but many good tools can be had for $100-$150 or so.  If you shop around you may find a tool with loads and pins to fit your application.  FYI the tool is a .27 caliber strip tool.  Loads are readily available at most big box stores.  The loads are color coded, going from the lowest, GREEN, YELLOW and then RED.  Start with the lowest power level and work up until your pin sets to correct depth.  Ramset, Simpson and Powers loads will work in the DX350 if they are .27 caliber strips.

There are a couple of ways to fasten 2 x material to steel columns, headers and trailer beds.  While there are several types and sizes, we want to cover our 1/4-20 x 2-3/4″ self driller with wings and it’s applications.  A flat self driller with wings is prefect for attaching your 2 x material to steel.  The wings ream out the 2x material and then snap off when they hit the steel and then the screw continues to drill and tap threads into the steel.  These screws will work in steel ranging from .110 (just under 1/8″) to .375 (3/8″ )   If your steel is too thin, the wings won’t break off and you will ream out the steel.  If your steel is too thick the screw will eventually bind up.  You will want to use the correct bit tip, a # 3 Phillips tip and use high speed on the drill or an impact driver.  The screw may start out a little wobbly in the wood but once it gets into the wood, it will support the screw better and then you can apply needed pressure to work through the steel.

Our flat head self driller for 2x to steel features a WAR ® coating that exceeds 1,000 hour salt spray resistance.  This not only makes it a good choice for exterior use when necessary but it is compatible with pressure treated lumber you may be using on a trailer bed.  The 1/4″-20 screw offers great pullout strength, 1,800 plus in 1/4″ steel and over 2,500 sheer in the same steel making a fastening that will hold up to heavy use.

While these screws are used in construction applications like 2 x 4 lumber to headers, many are being used in adding trailer boards to the trailer frame.  Again, the coating makes them compatible with pressure treated lumber and a better choice for trailers that are obviously exposed to the elements.  The larger diameter of the 1/4-20 will not only give you better holding power but can simply handle more load and vibration.  So if you are looking for a heavy duty screw to fasten down trailer boards, these are a good bet as long as your steel meets minimum thickness.


There are several types of eye lag poles designed for installing eye lags into the ceiling.  While originally designed for installing acoustical ceiling grid, eye lag poles are now being used in many trades including electrical, data comm, low voltage and signage.   We currently offer two types of eye lag poles, the Lagmaster Plus and the Purlin Master.  So what's the difference?  The Lagmaster Plus not only installs eye lags and ties the grid wire in place but has a small kit of interchangeable heads that can be switched out.  Heads included will install Sammy Screws & Vertigo type
