Liftmaster 25C20 coupler [K025C0020]

Fit function just right. Disconnect door end and the two bolts at operator end of rail. Test fit spline with door end on floor. Run operator to close door. It will stop where it should. Fit trolley back on rail and remove spline end. Manually turn screw at spline end until trolley is at the closed position, The rail use will show you where to stop for closed position, fit spline and bolt back up, start at operator end. This procedure will get start and stop points set automatically

Thank you it was pretty easy to find and order the part I needed. It was shipped on time, as well.
I will use Gatehouse supplies in the future as needed.

Although this is a small part, the cost was much cheaper than buying from a local dealer. The part fit perfect and I received it promptly.

Thanks Gatehouse

I recently had a part to my garage door opener break and none of the retail stores had it, all I was told was buy a new one. I found the part on your website and it was cheaper than I expected. The part arrived a couple days later and I was able to fix my door. Thank you very much.

I have a screw drive opener. The plastic collar shattered one day. Found gatehouse on line, found the part, better price than others, less shipping, got part fast, works perfect. Fixed for under 9 bucks!. Glad I found them. Thanks!
