Measure Door Clearance Before Purchase Ensure enough space between the door and frame. Sliding door locks need a gap over 0.46 inches. A smaller gap may prevent the lock from working. Simple Installation Installation is simple and tool-free. No drilling is required. Clean the surface before applying the sliding door child lock. Peel off the adhesive backing. Press the lock firmly onto the door or window. Adhesive Curing Time Allow the adhesive to set for 24 hours. This ensures a strong, long-lasting bond.
