A fumble-proof dog

August 7, 2018

We introduced the Three Legged Dog years ago, and we have heard from customers that it has been making metal stud installation easier ever since. What does a dog have to do with curved metal framing? A dog is a mechanical device that prevents movement by holding an object in place by clamping, holding, blocking or obstructing the object’s movement. Flex-Ability Concepts’ Three Legged Dog holds metal studs in place while still allowing for deflection or vertical movement of the top plate when necessary.

The difference between our product and others on the market is that ours are fumble proof. When an installer is on the ladder, it can be awkward to fasten a metal stud in place—with a competitor’s product. We have engineered a product that makes installers’ lives easier because the clip slides over the top of the stud as you lift the stud into place.

The installation process begins by cutting a stud short depending on how much deflection is needed. The Three Legged Dog then slides over the stud, with the “T” part in the stud, and twists into place. The stud can be fastened to the top track using screws or powder actuated fasteners. If positive attachment is needed, a screw should be installed in the slot but left loose to permit travel.

The product is available in 1 ⅝”, 2 ½”, 3 ⅝” (this works for 4″ studs), 6″, 8″ and 10″ sizes. It can be purchased from any distributor who carries Flex-Ability Concepts’ products. Visit for a list of distributors and more product information.

If this information needs some reinforcement, head to YouTube to watch Flex-Ability-Concept’s Frank Wheeler demonstrate how a Three Legged Dog works. We love showing our customers how simple these clips are to use!
