ACME Lead Nut – Plastic Threaded Mount Nut for Porch-Lift PL-RA Models

Upgrade or replace your worn-out lift nut with this precision-molded plastic ACME lead nut, compatible with legacy Porch-Lift Model RA (PL-RA) wheelchair lifts by ThyssenKrupp Access. Sometimes referred to as lift nuts, these components are vital to the smooth function of your screw drive or ball screw systems—especially in older Vertical Platform Lifts (VPLs) that rely on reliable thread engagement.

These lead nuts are designed to fit a variety of ACME-threaded drive screws commonly found in Porch-Lift RA units. Each nut features a right-hand thread, injection-molded plastic body for corrosion resistance, and compatibility with these ACME screws.
