Andersen Footbolts Installation Guide
Guide for Installing Andersen Footbolts on Gliding and Sliding Doors
Prepare the Door
Close the door or window completely to lock it. Place the footbolt flush against the edge of the inside moving door or pane so it sits perpendicular to the floor.
Position the Footbolt
With the rod retracted, place the footbolt so the bottom of the rod is 3/32” above the sill.
Measure and Adjust
Measure the distance from the edge of the door where you have placed the bolt to the edge of the glass pane in the door. Ensure this distance is more than 3/4”. If it isn't, use shorter screws than those included with your Andersen footbolt to avoid drilling into the glass. (Note: Glass typically extends 1/2” deeper into the door or window frame than visible, and the included screws will be installed 1/4” deep.)
Drill Holes
Using a 3/32” drill bit, drill holes 1/4” deep at the screw hole locations when the lock is in position. Insert the screws and securely affix the bolt to the sliding door.
Mark the Sill
With the door or window completely shut, lightly tap the top of the footbolt with a hammer to create an indentation on the sill. This marks where you should drill the hole for your footbolt.
Drill the Rod Hole
Release the rod of the footbolt and remove the moving door. Using a 1/2” drill bit, drill a hole for the rod to extend into. Place the plastic grommet included in the package with your footbolt into the hole and put the door back on its tracks.
Note:
An alternative to removing the moving door entirely is to mark the holes where the bolt should be affixed to the door. Carefully hold the bolt in place and mark where the rod extends into the sill. Do not install the lock until all the holes have been drilled. Measurements must be made very carefully with this method.
The entire process can also be replicated for an open vent position instead of a locking position if required. Instead of closing the door entirely, open it to the desired position and drill the hole at that point in the sill instead.
