MATEE Stainless Steel Security Automatic Gate Door Lock Spring Load Bolt Latch 2 Pack

I like the smooth ness of the sliding mechanism and the springs tension. I used it for what it was intended.

I used this to provide a positive latching mechanism for our attic pulldown that had lost a little bit of it's spring tension after a home renovation.Rather than going though all of the headach of replacing the springs, the swing arms, or (heaven forbid), the entire pull-down ladder, I added a couple of these to hold the lid closed, and they work wonderfully. The tension on the springs are good, the baseplates are solid (and have a little 'slope' build right into them), and attach securely.

Simple, clean, practical design made of strong materials for durability. Unobtrusive and enhances security. Always had a problem with locking double doors, as people forget to lock upper bolt, so closing the door will automatically lock it in place, allowing the deadlock to do its work properly.

Fit and finish is supreme. These are worthy of an interior finish if they had a slightly different design. Tolerances feel tight, edges are crisp but clearly some hand work went into them because they’re devoid of burrs. Holes are nicely countersunk. Comes with stainless screws as well. Fabulous quality

Nice smooth action, but not alot of throw. so you have to mount it perfectly in order to hold but not interfere with the door.
