Learn which tri wing hardware size fits your kennel and how to diagnose loose or missing screws. Step-by-step repair advice for a secure crate.
Quick answer
Use the 0.75" tri wing hardware for smaller kennels like Petmate Kennel Cab or Pet Taxi, and the 1.25" size for larger models like Pet Porter II or Ultra Vari Kennel. Match your kennel name and size to avoid a loose fit.
Why size matters for kennel safety
Using the wrong tri wing screw length can strip the plastic or fail to secure the door. The 0.75" pack is designed for compact carriers and kennels up to about 26 inches, while the 1.25" pack fits larger crates that need a longer bite into the wall.
Both packs include screws and wing nuts, but the thread pattern and shaft length differ. Check your kennel's molded label or manual—many Petmate models list the compatible hardware size.
What to do if you have mixed parts
If you inherited a used kennel or lost the original hardware, compare one existing screw to the descriptions. The 0.75" screws are noticeably shorter and fit flush with thin-wall carriers. The 1.25" screws extend further and are meant for thicker kennel walls found on larger models.
When in doubt, remove one screw and measure from under the head to the tip. This quick check prevents buying the wrong replacement.
Diagnose your kennel hardware issue
- Symptom: Screws are loose, missing, or the door rattles when latched. You may see stripped plastic holes or screws that won't tighten.
- Likely cause: Wrong tri wing size: 0.75" screws used in a kennel that needs 1.25", or vice versa. Also possible: worn latch or stripped screw holes.
- Corrective action: 1) Identify your kennel model and size. 2) Select the matching tri wing pack: 0.75" for smaller carriers/kennels, 1.25" for large models. 3) Replace all screws and wing nuts. 4) If the door still won't latch, replace the latch with the Short Replacement Latch. After replacing hardware, test by shaking the closed kennel—if it still rattles, check the latch.
- Stop or choose another option: If the plastic holes are completely stripped or cracked, hardware alone won't fix it. Consider a replacement kennel or a repair kit with threaded inserts. Stop if the kennel has structural damage. For cracked plastic, do not force new screws—this can worsen the damage.
