A comfortable fit starts with measuring
We check panel size, glass type, mounting height and sliding-door clearance before recommending a product. Toughened glass needs a new panel with the opening prepared before toughening.
Pet-Tek
Clear Catwalk and Dogwalk frames blend into your glass while giving cats and dogs their own way outside. Choose the usable opening that fits your pet, then we check the glass thickness and sliding clearance.
Sizes below flap sizes openings (width × height), rather than the outer frame or glass cut-out. Slimline and dual-glaze versions depend on your panel.

PetSafe aluminium
The Staywell aluminium range combines a metal frame with a soft flap and slide-in closing panel. Four sizes cover small cats through to larger dogs.
Glass fitting needs an individual assessment. PetSafe lists this model for wood, metal, PVC and walls; a suitable mounting solution and replacement panel must be confirmed before a glass installation.
