The Staywell 932 Magnetically Operated Cat Flap does not rely upon batteries or electricity to operate. Instead, the force of the magnetic 'collar key' activates a latch within the pet door to release the flap.

The door includes a 4-way lock which has been significantly improved over the original design.

Since this pet door is self-framing, it may be installed in any door including solid or hollow core, metal (aluminum or other non-magnetic material), insulation filled etc. Adjustment range for the self-framing feature is 0" to 2". It should not be installed in a door made from steel or other magnetic material. 

Hint: How to tell--Take any magnet and see if it's attracted to the door you intend to use.

Reversed installation (turning the pet door around so that it controls from the inside rather than from the outside) will void the warranty.

Staywell provides one collar key is provided and spare keys with collar may be ordered at "Collar Keys"

Hot Tip: You'll need your own collar for the collar keys listed here. But Staywell has a nice collar of their own offered with collar key that will work fine with the 932. It's on the Cat Flap Collar Keys page.

Staywell believes that this pet door is suitable for cats to about 15 lbs. When used for a dog, we'd suggest shading that value back a bit. As always, please measure before purchase.
