Product Details

Product Details

This sliding door lock is designed to solve a common issue with pet door setups. When a panel insert prevents your original lock from engaging, it creates a gap in security. This lock restores that missing function by creating a new, fixed locking point directly on the frame.

The steel construction provides a solid, reliable hold that keeps doors and windows from shifting or being opened from the outside. Once installed, it maintains consistent pressure, helping ensure the door stays firmly in place.

Installation is straightforward and uses included hardware to anchor the lock into the frame. It can be positioned at the top or bottom depending on your door configuration, allowing it to adapt to a wide range of setups.

Designed to blend in with your existing door frame, the low-profile look keeps your setup clean while adding a meaningful layer of security. It’s a simple upgrade that brings confidence back to your sliding door without interfering with your pet door’s daily use.

  • Installation is flexible. Position the Slidelock anywhere on your sliding door where the lock plate can securely attach to the door frame. Find the arrangement that best suits your home.

Step 2 Prepping the Lock

Prepping the Lock
  • Loosen the two screws on the side of the lock and remove the sheet metal cap.
  • You only need to loosen the side screws—no need to remove them completely to take off the cap.

Step 3 Mount the Lock

Mount the Lock
  • Place the lock where you want it and make sure it lines up with your chosen plate. Secure it with the six short screws.
  • Do not screw into glass—ensure you are clear of the glass area before installing.

Step 4 Install the Locking Plate

  • Slide the door or window closed. Now, position your Lock Plate or Hole Plate where it belongs and secure it with the long screws.
  • If you're using the Hole Plate, grab a drill and make a clearance hole so the lock can latch properly.

Step 5 The Moment of Truth

The Moment of Truth
  • Give the lock a quick test—does it engage and disengage smoothly? If yes, you’re golden! Put the metal cap back on and tighten those side screws.
