The Perry Foam Diskit 50590 5″ Hook & Loop Low Profile Back-Up Pad is a durable, professional-grade sanding pad designed for demanding sanding and surface preparation applications. Its firm, low-profile construction provides excellent control and consistent support for 5-inch hook-and-loop abrasive discs.
The 50590 features a hook attachment surface that allows compatible sanding discs to be quickly installed, removed, and changed as you progress through different abrasive grits. Unlike PSA-style pads, the hook-and-loop system does not require adhesive-backed discs, making abrasive changes fast and convenient.
Constructed using Perry Foam’s durable polyurethane foam and lightweight magnesium components, the pad is designed to withstand repeated professional use while providing a secure and stable sanding surface. Its firm density and low-profile design make it particularly useful when greater control and a more positive sanding action are desired.
The 5-inch diameter is an excellent size for fiberglass and composite fabrication, gelcoat repair and refinishing, marine repair, automotive bodywork, woodworking, metalworking, and general industrial surface preparation.
