AmesburyTruth 3489 Dual Point Sliding Door Mortise Keeper

The AmesburyTruth 3489 is a dual point keeper designed to work with sliding patio door mortise locks. It provides the strike points that the mortise lock engages when the door is secured.

This keeper is offered in two finishes: model 3489-63 in Yellow Zinc Dichromate over 1010 cold-rolled steel, and model 3489-84 in mill/raw 304 stainless steel. Choose the finish that matches your existing hardware and your exposure to weather or salt air.

The keeper mounts to the door jamb with four screws through the pre-drilled holes and sits flush in a mortised pocket. Please confirm the pocket depth and screw hole layout of your existing keeper before ordering.

“Ordered a hard-to-find Pella handle set from the website. Handle arrived as promised and fit perfectly. It was listed as blemished but the chip was nearly invisible and on the exterior of a seldom used door. You saved me $450!”
