Expert Verdict — Reviewed by the SuperArbor Pro Desk
The 1.75 in. length bridges common gaps between the 1.25 in. and 2 in. options for single-layer insulation over steel decks. Match the length to assembly thickness and deck embedment per JM's drawings, and maintain the fastener spacing required by the wind uplift design. Pair with JM plates for membrane attachment where specified.
Fastener points are sharp; wear cut-resistant gloves and eye protection when handling and installing, and follow the manufacturer's instructions and local code.
