Master Lock Pro Series Hidden Shackle Padlocks - Keyed Alike

FITMENT: To ensure proper fit, measure the hasp/latch on your trailer door. Size dimensions are illustrated in the provided schematic. Also, check the depth of the hole on the hasp. If the center of the hole is more than 13/16 (20mm) from the edge, the pin will not engage, as the depth on the lock would be too shallow. Many times, latches are poorly manufactured and the holes are carelessly placed off center, thus creating fitment issues. If you are inclined, you can modify the hasp.

These locks offer ideal protection against bolt cutter attacks. The extra heavy-duty 2-7/8" wide padlocks are ideal for all outdoor applications when needing multiple locks that utilize only one key. The same key opens all locks. Each lock comes with two keys, therefore you will receive a total of eight keys with the purchase of this 4-pack.

ProSeries Reinforced Zinc Die-Cast: Zinc castings are chosen for countless decorative and functional applications due to their unmatched properties and economics. Zinc alloys provide high strength and toughness, with impact resistance higher than cast aluminum alloys, plastics, and grey cast iron. They offer high strengths (up to 60,000 psi) and superior elongation for strong designs and formability for bending, crimping, and riveting operations. Zinc alloys are also non-sparking, making them suitable for hazardous location applications such as coal mines, tankers, and refineries.

This pack includes four (4) high security ProSeries Padlocks designed for commercial/industrial applications, keyed alike with a total of 8 keys. The 2-7/8" (73mm) wide reinforced zinc die-cast lock body is ideal for transportation, vending, and many other applications.

FITMENT: Please refer to the product details below to ensure these locks will work for your needs.

ATTENTION: Ordering two 4-packs does not guarantee that they will be keyed the same. To ensure you receive two 4-packs keyed alike, you must order the 8-pack.

Refer to the image for shackle dimensions: A: 3/8in (9mm) B: 19/32in (15mm) C: 1-23/32in (44mm). The lock body conceals the shackle, and the fully shielded 3/8 (9mm) diameter hardened boron alloy shackle offers resistance to cutting and prying.

The high-security, re-keyable 6-pin cylinder with spool pins is virtually impossible to pick and comes with a lifetime guarantee. This lock is also available with BumpStop Technology, search for 6271NKA in Amazon's search window for more information.
