Purpose & fit

The Best 21BWC weather cover shields 21B series padlocks from the elements. It fits both standard and long shackle versions for buyers who need outdoor security hardware to stay functional in rain or dust.

Practical limits

The guard accepts a maximum shackle diameter of 5/16 in and is built from black plastic with a transparent finish. Weather resistance is rated yes, so the cover handles exposure without degrading the lock mechanism underneath.

Upgrade path

This cover replaces an unprotected shackle or a worn guard that no longer seals out moisture. The jump is worth it when an existing 21B padlock shows corrosion or when new installations must meet outdoor durability requirements from day one.
