Safety Lockout Padlock

The Master Lock S33KAS3RED is a thermoplastic safety padlock designed for lockout and tagout procedures. Its red body measures 1 13/16 in high by 1 3/8 in wide with a 11/16 in thickness. A 3/16 in diameter stainless steel shackle provides 1 1/2 in of vertical clearance. The keyed-alike cylinder ships with two keys and labels for identification.

Suited for Single-Key Systems

This padlock suits maintenance teams that need multiple locks operating from one key. The non-removable key design prevents the key from being withdrawn while the shackle is open. Chemical-resistant thermoplastic withstands harsh industrial environments. Facilities requiring unique keys per lock or a different shackle height should consider other options.

Keyed Alike Cylinder

The defining specification is the keyed-alike cylinder configuration. Every padlock in the set opens with the same two included keys, simplifying key management for authorised personnel. This feature determines whether the lock integrates into an existing single-key safety programme or if a keyed-different variant is required.

Questions about this item

Will the 3/16 in stainless-steel shackle need periodic lubrication or replacement?

The stainless-steel shackle resists corrosion and chemical exposure, so routine lubrication is not required; replacement is only needed if physical damage occurs.

What is the first limitation you hit when the padlock is used continuously in a lockout programme?

The 1 1/2 in vertical shackle clearance and 5/8 in horizontal clearance set the maximum hasp or chain size that can be secured.

Does the thermoplastic body become hot or noisy when the lock stays in place all day?

The red thermoplastic body is chemically resistant and non-conductive; it does not generate heat or noise during extended use.
