Invented by Colchester, Vt., contractor Eric Kurtz, Smart Bracket Staging brackets are designed to hang over the top plates of a framed wall and support standard aluminum staging planks (wood ones can be used as well). Each pair of brackets is rated at 1,000 pounds, so only two brackets are needed to span up to 24 feet (the longest aluminum plank available). The end brackets ($299 each) include a rail post with a pocket to hold a 2×4 guardrail. Accessory Smart Rails ($159 each) provide interim guardrail support. smartbracketstaging.com
