Padlock KA 1-1/2 In H 4 Pin

This laminated steel padlock uses a Master K7 keyway and opens with key number P241. It is keyed alike for users who want multiple locks operated by a single key. The rectangular body measures 1 1/16 in high by 1 1/8 in wide with a 1/2 in thickness. The 3/16 in diameter steel shackle provides 1 1/2 in of vertical clearance and 1/2 in of horizontal clearance.

Fitting the shackle and key

Insert the shackle fully until the locking mechanism engages with an audible click. The 4-pin cylinder turns smoothly when the correct key is fully seated. Forcing a partially inserted key or turning before the shackle is locked can jam the pins. The single bumper helps reduce rattle but does not prevent water ingress.

Durability under repeated use

The laminated steel body resists cutting and prying better than solid brass equivalents of similar size. The 4-pin mechanism maintains consistent operation through thousands of cycles when kept free of grit. Without a weather-resistant rating, prolonged outdoor exposure will eventually cause surface corrosion on the steel components. The lock is not rekeyable and does not accept an interchangeable core.
