Ranger Lock RGRU-0L 10 in padlock guard for trailer roll-up doors

Trailer Roll-Up Door Guard

The Ranger Lock RGRU-0L is a hardened steel padlock guard designed specifically for trailer roll-up doors. It provides a robust physical barrier that protects the padlock shackle from cutting or prying attempts. The black finish offers weather resistance for outdoor exposure. This guard is built for owners securing cargo trailers, storage units or commercial roll-up doors.

Upgrade From Exposed Shackles

This guard replaces the practice of leaving a padlock shackle fully exposed to bolt cutters or saws. The jump is worth it when the value of the trailer contents justifies a hardened steel shield that covers the shackle. It accepts shackles up to 3/8 inch diameter and vertical clearances from 1 1/4 inch to 2 1/2 inch high. Buyers needing protection for larger diameter shackles or different lock body styles cannot use this model.

Verify Shackle And Clearance

Before ordering, confirm your padlock shackle diameter does not exceed 3/8 inch. Measure the vertical shackle clearance to ensure it falls between 1 1/4 inch and 2 1/2 inch in height. Check that the roll-up door hasp or latch geometry allows the 10 inch guard body to sit flat without interference. Ensure the mounting hardware suits the door material thickness.
