Buying Guide

Match trim to edge thickness

Choose a profile sized for your panel edge (examples include 1/16", 3/16", and 3/8") so the gripping tongue or insert secures properly without gapping

Check leg depth for mounting surface

Pick a trim with a leg length that covers and protects the exposed flange—options here range from about 17/32" to 9/16" to 5/8" leg depths

Prefer PVC with mechanical grip

PVC edge trims with a gripping finger or tongue provide a tight seal against vibration and moisture, improving long-term resistance to marine conditions

Consider aluminum clip reinforcement

Profiles that include aluminum clips or metal inserts increase retention strength and reduce deformation on thin or soft substrates

Balance length and value

Trim rolls are commonly offered in long lengths (e.g., 25' options) — compare price-per-foot and ratings to find the for large projects
