50 mm laminated steel padlock

The Brinks 677-52001 is a 50 mm laminated steel padlock with a boron steel shackle for superior cut resistance. It uses a five-pin cylinder to increase pick and pry resistance and a dual stainless-steel locking mechanism for added security. The keyed-different design ensures each lock operates on its own unique key. A powder-coated finish helps the padlock withstand harsh outdoor conditions.

Thermals noise and power draw

This mechanical lock has no electrical components, so it produces no heat, noise or power draw during use. The form-fitted plastic top and bottom bumpers protect surrounding surfaces from marring when the lock is handled or shaken. No batteries, wiring or cooling are required for operation.

Security specification that decides fit

The 50 mm body width and boron steel shackle dimensions determine whether the padlock fits your intended hasp, chain link or trailer latch. Buyers who need a narrower body or a longer shackle clearance for thick chain links will find this model unsuitable. Verify the exact shackle diameter and internal clearance against your mounting hardware before purchase.

Questions about this item

How do I install the Brinks 677-52001 padlock on a chain or gate without marring the surface?

Insert the boron steel shackle through the hasp or chain link, snap the form-fitted plastic top and bottom bumpers into place, then press the shackle down until the dual stainless-steel locking mechanism clicks securely.

What maintenance will the 50mm laminated steel padlock need over time?

Periodically spray a dry PTFE lubricant into the five-pin cylinder and shackle holes to prevent grit buildup; wipe the powder-coated body clean and inspect bumpers for cracks, replacing them if they split.

What is the first limit the Brinks Commercial XT padlock hits under sustained outdoor use?

The powder-coated finish resists harsh conditions, but prolonged exposure to salt air or industrial chemicals will eventually degrade the coating and allow surface corrosion on the laminated steel body.
