Product: Master Lock Pro Series - (3) Hidden Shackle Padlocks Keyed Alike 6271KA-3
Brand: Master Lock
Color: Chrome
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. 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. You can modify the hasp if you are inclined.

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 six keys with the purchase of this 3 pack. ProSeries Reinforced Zinc Die-Cast Why Zinc Castings?
