Seco-Larm SD-995C Fail-Secure or Fail-Safe Electric Door Strike for Metal Doors, Static Strength 1000 lbs. (454kg), Can Be Used with Virtually Any Cylindrical Door Locking System

Holds the door much tighter than the generic locks it replaced.

Product works as intended, very happy.

They aren't kidding when they say this is for metal doors. It's deeper than the one designed for wood door frames, so you'll end up cutting into the door post to install it if you install it in a conventional wood door/frame.Other than that and the dainty, excessively fine wires (that don't really look like they are up to the 2 amps this is supposed to draw), i've got no complaints. It works as advertised.BTW do yourself a favor and get an oscillating multitool if you need to cut a new door to install this. It's a fantastic tool for the job.

I have used these locks on 5 projects so far and have never had an issue installing them. It comes with a great adhesive template, and detailed instructions. It can be setup for 'Fail Safe' [open without power] or Fail Secure [locked without power]. As all door jams are different, I have had to on occasion do more extensive work on the inside of the strike area to allow this lock to fit into the jam correctly. Device worked perfectly and I feel very secure in it's operation.

The item arrived as expected and as described in the picture. The default for the electric strike is fail secure (locked). With a minor adjustment it can be changed to unlocked. Not sure why you would want that but it has that ability. I used this for a commercial steel door.Would buy this again.

This is a great product, was as described.This item is durable and easy to use.Was delivered on time and the price is just.

Pros : Excellent Quality, Cheap Price.Cons : A bit loud with the buzzing...

Door strike works great in my daycare. It was easy to install and it helps in keeping the entrance door secure.
