direction of locking on cat doors

4-way lock

Unlocked - This setting allows entry in both directions.

Locked - This setting allows no entry in either direction.

Out-Only - When the pet goes out, he cannot come back in again. A possible use for this setting would be a case where you want the pet out during the day. You'd set the flap on "out only" in the morning.

In-Only - When the pet comes in, he cannot go back out again. One possible use would be a case where you want the pet in at night. You set the pet door for "in only" in the evening.

Cat flaps with 4-way locks always have rigid flaps which are necessary for the mechanism to work.

The Petsafe 4-Way Locking Cat Flap, White (previously the Staywell 300 4-way locking cat flap) has a flap dimension of 6 1/4" w x 5 1/2 " h

It is self-framing from 0" to 2 1/4" out of the box and tunnel extensions are available which may be added by the user to increase the maximum to any length.

For example, a self-framing wall mount for any thickness wall could be implemented by simply adding the tunnel extensions.


Staywell 4-Way Lock Problem Areas and Improvements

Complaints have been received that some pets could force open the 4-way lock.  Also, some have found the imprinted numbers on the knob difficult to read.

Improvements Made

The new Staywell 4-way lock is more than 2.5 times secure as a result of these specific improvements:

  • Increased tab length:  Greater surface for lock to engage
  • Raised teeth interlock:  added feature to prevent lock from stripping.
  • Lock assembly moved for greater leverage.
  • Numbers were made more visible on the improved knob design.

Customer Reviews

Set Direction
  • lousy useless lock review by Cheddie
    5 1 lousy useless lock

    The lock being in one corner = cats can push through. Even my little 10 lb cat pushed thru. The flap has been pushed thru so many times, now, it has a big crack down the middle, which I've taped up with clear Gorilla tape, so the flap still works as a flap. But it does not lock. I would never buy a flap/ door like this again.

  • basically good, but could be better review by ilona
    5 3 basically good, but could be better

    The basic construction of this is ok. The cats use it
    regularly and the dial (for in-only, out-only, all open, all closed)
    is a bit small and flimsy. A determined cat could easily defeat
    the locking functions. The "tunnel" connecting inside part
    and outside part does not connect securely, keeps coming
    unconnected. This makes cleaning difficult.

    If there were some real competition for this product, maybe
    the manufacturer would improve it?

  • good to very good review by catherine louise
    5 4 good to very good

    we use this on a garage side door.....yes the old one was better but no complaints about this

  • Not happy review by Patsy
    5 2 Not happy

    It doesn't fit properly, the tunnel only has 4 tiny places for it to fit together and it won't stay put. And it has lots of seams that get really dirty. As far as the workability, the cats get in and out fine. The old one was better and if I could find it again I would buy it!!

Limited Warranty for PetSafe Certified Refurbished Products

Effective January 1, 2010

For purposes of this limited warranty, “PetSafe Certified Refurbished Products” means buy-back products, returned products, pre-owned products, and/or scratch & dent products that PetSafe has:

  • Fully tested 
  • Refurbished by replacing any defective modules identified during testing 
  • Thoroughly cleaned and inspected 
  • Repackaged (including appropriate manuals, probes, wire, new boxes, etc.) 
  • Re-inspected prior to being sold 

PetSafe Certified Refurbished Products may have small cosmetic blemishes. PetSafe warrants that each PetSafe Certified Refurbished Product will be free from defects in material or workmanship for a period of ninety (90) calendar days from the original date of purchase. During the warranty period, PetSafe will, at its option, replace with new or refurbished products or parts, any products or parts determined to be defective. In the event of a product defect, these are your only remedies. This warranty gives you specific legal rights and you may also have other rights, which vary from state to state.

This limited warranty covers only product issues caused by defects in materials or workmanship during ordinary consumer use and does not cover product issues caused by any other reason, including, but not limited to, product issues arising out of or related to commercial use, acts of God, misuse, limitations of technology, or customer modification of any part of the PetSafe Certified Refurbished Product. This limited warranty does not cover consumables, such as treats, batteries, or fuses. This limited warranty is invalid if the factory-applied serial number has been altered or removed from the product. This limited warranty is valid only in the United States.

All express and implied warranties, including without limitation any implied warranties of merchantability and fitness for a particular purpose, are limited in time to the term of this limited warranty. No warranties, whether express or implied will apply after the expiration of the limited warranty period. Some states do now allow limitations on how long an implied warranty lasts, so this limitation may not apply to you. Except as provided in this warranty and to the extent permitted by law, PetSafe is not responsible for direct, special, incidental or consequential damages resulting from any breach of warranty or condition, or under any other legal theory. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above exclusion or limitation may not apply to you.
