xSecure your trailer with the Master Lock 1471DAT
The Master Lock 1471DAT combines durability with practical design to help protect your trailer. Crafted with a solid brass body and finished with chrome plating, this lock is built to resist daily wear while maintaining a clean, low-profile look on the coupler. A weather-tight cap seals out moisture and road spray, helping the lock stay reliable in varying conditions from rain-soaked campsites to dusty staging areas.
Key measurements are designed for broad compatibility. The lock features a 3.4 inch (3-4/10) shackle length and a 9/32 inch diameter pin, a standard size that fits a wide range of couplers. A precision 4-pin tumbler mechanism adds an extra layer of protection against casual tampering, while a K1 key blank enables straightforward replacement or rekeying alongside existing Master Lock products.
