Frequently Asked Questions
What is a grommet pad?
A grommet pad has through-holes that allow fasteners to pass straight through, no countersink. It sits between stainless steel hardware and the aluminum deck substrate, providing galvanic isolation and distributing fastener loads. This particular grommet pad also has a 1.5" center passthrough for routing cables, hoses, and wiring.
Can this pad be used on a fiberglass deck?
Yes — this pad is designed for fiberglass pedestal-wall installations. The through-holes accommodate 1/4" fasteners (5/16" hole diameter), and the 1.5" center passthrough routes cables and hoses. The pad distributes fastener loads over a wider surface area to prevent deck damage while providing galvanic isolation between stainless steel and aluminum.
What size fasteners do I need?
The six through-holes are 5/16" diameter sized for 1/4" fasteners. Use 1/4"-20 stainless hardware for best results.
