Introduction

A plunger lock uses a spring-loaded pin that extends into a strike plate when the door closes.

  • Keyless push-to-lock action speeds up daily access
  • Compact size fits narrow frames without extra hardware
  • Available in keyed-alike sets for multiple storage units

Pick the cylinder length that matches your panel thickness.

FAQs

Stainless-steel or zinc-plated versions resist weather, but covers help prolong life in direct rain.

Many cylinder styles accept new pins, allowing you to match keys across multiple locks.

Yes. A small strike plate or hole in the frame catches the plunger and keeps the door secure.

Most snap into a pre-drilled hole and are held by a retaining clip or nut on the rear side.
