This ADEL Handle Spring is a replacement part for both the Trinity-788 & DIY-3398 fingerprint door locks.
The Adel Trinity-778 and Adel DIY 3398 lock has one weakness. The handle if forced downwards breaks the spring. Under normal use the spring should last the lifespan of the product, but under sever force the spring breaks.
Our Tech Support department is more than happy to walk you thought the replacement procedure.

Outstanding customer service!Review by Bryan
Installing the spring is very hard without the right tools. I’m giving 4 stars for the spring only because this company is the only one that gives Tech Support on installing it.
I talked to Ralph the Tech Guy. He was very friendly and patient with me. Thanks!!
