Tailbone215 0 Posted January 19, 2011 You might want to use beam clamps for this type of job. We use them for mounting boxes and conduit. Works great and gets you out quick. http://www.hvac-runner.com/3-8-Top-beam-Clamp-85.html Share this post Link to post Share on other sites

Tailbone215 0 Posted January 20, 2011 Heavy duty toggle bolts Nope! Too much drilling even if you wanted to use them. You definitely don't want to be drilling structural steel supports such as these. They make a whole series of beam clamps for every application. Learn how to use them and your life will be a lot easier. Share this post Link to post Share on other sites

Trust me i've done it many times and is the quickest and cheapest solution OK, I am assuming you're using a large fender washer as you run the risk of having the toggle shift and fall between the gap? I've seen this done before without the washer and it surely was a comical sight. Share this post Link to post Share on other sites

ChrisH 0 Posted January 22, 2011 Beam clamps very easy.... doing this at a job right now. Beam clamps are easy. Whether you use them to mount a junction box first and the camera to the j box or just using them to mount the camera directly. The other thing the beam clamps do for you is no drilling of structural members. This may sound goofy, but in some areas the building inspectors are very strict about this. Unless you want to get a structural engineer to sign off saying that the holes you made are ok, just just the beam clamps and walk away with no worries. Just my 2 cents.

We all know a hole for a 1/4 x 20 bolt isn't going to cause any structural problems, but it surely will cause a lot of grief as you mention. Love beam clamps as they prevent a lot of this misery. Also, I know most of these installers are also using EMT or other suitable conduit instead of draping the cable over the support beams. Share this post Link to post Share on other sites

bpzle 0 Posted January 23, 2011 Here's a picture of something similar to what we just discovered and like... That isn't it exactly... we use bridle rings and beam clamps and/ or ceiling grid wire clamps. Pretty slick looking, and it makes pulling/ removing/ rerouting easy! Much better than J hooks in my opinion... Share this post Link to post Share on other sites
jeromephone 6 Posted January 23, 2011 caddy fasterners low voltage book all kinds of good stuff amen to beam clamps! The pics are correct as running cat 5/6 wire now requires a wider support than just the bridal ring they J hook or the yellow plastic insert fullfills the spport requirement.
