Description

This listing is for 1 keyed alike lock - 2 keys included. The hardened diecast zinc body is strong, durable and resists corrosion. Pro Series Padlocks are designed for Commercial/Industrial applications. Ideal for transportation, vending, gates, and industrial uses. These Locks FEATURE BumpStop Advanced Cylinder Technology (For explanation see more product details below). HIGH SECURITY 6-pin cyclinder for maximum pick resistance. Removable cylinder for replacement or repinning. BOLT CUTTER TOUGH - fully shielded hardened boron alloy shackle offers impossible to cut and pry resistance features. DIMENSIONS (see image) - A) 3/8 (10mm), B) 19/32 (15mm), C) 1-23/32 (44mm) Width 2-7/8 (73mm) 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.

ProSeries Reinforced Zinc Die-Cast

Why Zinc Castings?
For countless decorative and functional applications no other material and process can match the properties and economics of zinc die casting.

Toughness:
Few materials provide the strength and toughness of zinc alloys. Impact resistance is significantly higher than cast aluminum alloys, plastics, and grey cast iron.

Strength & Ductility:
Zinc alloys offer high strengths (to 60,000 psi) and superior elongation for strong designs and formability for bending, crimping and riveting operations.

Anti-Sparking:
Zinc alloys are non-sparking and suitable for hazardous location applications such as coal mines, tankers and refineries

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $14 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for Master Lock products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
