If you need a jobsite guardrail system then Diamond Tool has what you need. For traditional 2 x 4 guardrails choose the metal boot. It’s sturdier than plastic models and can be fastened to concrete decks using ¼” concrete screws. Our Slab Grabber is an excellent choice for quick and easy set-up for various decking installations. For tremendous versatility, super fast installation and years of use, select the 52″ metal post. It can be used with 2 x 4’s or snap-on metal rails and has a variety of mounting and fastening options available for just about any surface. Choose floor/stair, wall or gusset brackets.
