Forge Defender 2A837C FAQs
How far does the Forge Defender shackle adjust?
The Defender 2A837C has an adjustable rigid shackle that can be set from 1.57 to 3.85 in. The adjustable range provides extra reach for compatible gates, fence latches, lockers, sheds and storage hardware where a fixed shackle may be too short.
How thick is the Forge Defender shackle?
The hardened-steel shackle measures 0.27 in across. Before ordering, check that the opening in your gate latch, hasp, locker or other hardware is large enough for the shackle to pass through.
Will the Forge Defender fit my gate, shed or locker?
Fit depends on the size and position of the locking point. Measure the opening diameter, required shackle reach and surrounding clearance before ordering. The shackle adjusts from 1.57 to 3.85 in, but the adjustable design does not guarantee compatibility with every gate, hasp or locker.
Does the Forge Defender require a key?
No. The Defender 2A837C uses a resettable 4-digit combination for everyday access, so there is no personal key to carry or keep track of.
Can I change the combination on the Defender 2A837C?
Yes. The 4-digit combination is resettable, allowing you to set and change your own code. A 4-digit system provides 10,000 possible number combinations from 0000 to 9999.
What are the dimensions and weight of the Forge Defender 2A837C?
The standardized lock dimensions are 2.53 × 4.61 × 0.65 in, and the unit weight is 6.48 oz. The hardened-steel shackle measures 0.27 in across and adjusts from 1.57 to 3.85 in.
