## Overview

The Master Lock 5NKA-4 set includes four heavy-duty, keyed-alike padlocks with 8 keys, designed for commercial and industrial use. Featuring a 2" laminated steel body, 1" clearance hardened boron alloy shackle, and proprietary BumpStop technology, these locks offer superior cut and pick resistance. Rustproof and pry-resistant, they are the go-to security solution for job site gang boxes, KNAACK, RIDGID, and other construction storage containers.

## Description

FEATURING BumpStop TECHNOLOGY - Lock bumping a surprisingly simple method of breaking in through locked doors and padlocks - is undoubtedly the newest emerging threat to personal property security. And virtually all locks in use today are particularly vulnerable to bumping. Until now. BumpStop Advanced Cylinder Technology employs an innovative, patent pending design which utilizes a unique reverse rake tapered driver pin, high performance springs and tightly machined cylinder chambers. During a bump attempt, this design prevents the transfer of force from the bump key to the pins and therefore blocks rotation of the cylinder so that the lock remains locked.inquire and we can normally have them in a couple of days.

Review: Good locks - The locks were exactly what we wanted
Review: Sturdy!! - So I tried to return them before they arrived because they kept changing the delivery date. Got pushed out by an over a week. I'm glad I couldn't cancel the order. They arrived and are super heavy and sturdy. Bigger than the standard ones I would have gotten at HD. Love the two keys per lock. So I got 16 keys with the 8 locks. A few of the keys didn't work - like maybe 3. I'll run by the locksmith and see if he can fix them. They feel good and heavy. They open super easy. Yupp. Glad I didn't return them.
