Muzata 20Pack Extension Connector for 17mm-Wide U-Shape LED Channels LCB1

These work very well to connect and hold the aluminum channels. I would recommend using these in lieu of the small flimsy clips that come with the channels. You can cut these in half and install them as you would the small flimsy clips.

Easy to install, one piece holds and joins two rails together

These longer clips work soooooo much better than the shorty clips that come with the track. These should be the clips that ship with the track, shouldn't have to pay extra for them. Work great for lining up the tracks.

LED channel joiner works to keep the extrusions aligned as it should and grips the channel well, The included screws were of good quality.

If you are installing track for the LED strings, these are great for getting piece to piece straight and secure. Very easy to install. Much better than the narrow original mounts that are difficult to get length to length square

I used to attach 6 ft channels for strip lights. They worked great and gave a professional look.

Great but out. Also may be difficult to put them on the led strip housing. Tight and tough. Doesn't bent and is strong enough to support the connecting led led strip housing for install. Great buy but be careful. Can cut yourself on them during install. lol oops?

I had never installed the aluminum LED runners before and thought these would help me keep a 13’ run of multiple pieces straight and in-line at the joints. Boy was I right. Although I think the aluminum track pieces I purchased were great, they lacked longer clips such as these. They installed super easy and made my finished run look seamless. The fastening hardware was just right for applying to wood with a small pre-drilled starter hole. I’d buy these again.
