Be sure that the hole is large enough to eliminate any binding of the slide bolt.
How to install a door slide bolt.
An outside sliding is a door in which the moving door is on the outside of the house whereas an inside sliding places the moving door on the inside of the house and the fixed one on the outside.
Close the door up until the keep touches the door frame.
It will be necessary to drill deep enough to allow full extension of the slide bolt in order to secure the lock.
To install your security slide bolt lock you must first determine whether your door is inside sliding or outside sliding.
The closer it is to the center of the door the more.
With the door bolt now fixed firmly to the door the final job is to fix the bolt keep onto the door frame.
Glue this to the door where you want the bolt lining up the front edge of the plywood with the edge of the door.
Extend the bolt out slightly and push the bolt keep over it.
Mark fixings for door keep.
Cut a piece of plywood larger than the size of the bolt.
How much strength do you need the bolt to have.
If you need a stronger latch it will require a lot more work.
Then screw the bolt onto the plywood.
A typical placement is one or two feet above the knob but it can be lower.
