## Overview

The Master Lock 142DCM is a compact, blue vinyl-covered aluminum padlock designed for indoor and outdoor use. Featuring a hardened steel shackle and a 4-pin cylinder with dual locking levers, it offers reliable cut, pick, and pry resistance. Ideal for gym, school, or storage lockers, this lightweight yet durable lock combines corrosion resistance with smooth key operation, backed by a limited lifetime warranty from a trusted brand.

## Description

The Master Lock 142DCM Covered Aluminum Padlock with Key features a 1-9/16 in. (40mm) wide blue vinyl covered body for scratch and corrosion resistance. The 1/4 in. (6mm) diameter shackle is 7/8 in. (22mm) long and made of hardened steel, offering extra resistance to cutting and sawing. The 4-pin cylinder prevents picking and the dual locking levers provide resistance against prying and hammering. The Limited Lifetime provides peace of mind from a brand you know and can trust.

Review: Highly recommend this purchase - I bought the Master Lock 142DCM for my gym locker, and it has been a fantastic purchase. The lock features a vibrant blue vinyl-covered aluminum body, which is lightweight yet feels sturdy. Because of the vinyl coating, I do not have to worry about it scratching my locker door or rusting if I happen to leave it outside in the rain. It comes with matching keys, and the mechanism turns smoothly every time without any jamming. Pros: - Lightweight aluminum body with a protective vinyl cover to prevent scratches. - Smooth key operation; no sticking or struggling to open. - Compact size makes it ideal for standard gym, school, or storage lockers. - Affordable price point for reliable security. Cons: - It is a smaller lock, so it is meant for low-risk security (like gym lockers) rather than heavy-duty outdoor security like storage sheds or gates. - The shackle clearance is a bit tight, so make sure to check your locker's latch thickness before buying. Overall, this is a reliable, budget-friendly lock that gets the job done with zero hassle. I would definitely recommend it to anyone needing a dependable small lock for school, the gym, or indoor storage.
Review: Well made lock - Though it is an inexpensive lock, it seems to be well-made for its size. Where I have it in use is in the weather and doesn’t seem to affect it. I lock and unlock it often and works smoothly every time.

Simple lock, works great so far, no complaints! Seems sturdy, but I guess that will be tested over time. Glad it wasn’t very expensive either.
