There are a few options for cutting and extending the Prolux 24V RGBW tape light.

6″ Cut Tape Connector: Example: You installed tape and have 15 feet left over that you wish to use in a different place, but because you cut it to length you no longer have the leads that attach to the decoder. You would install this at the cut point on the tape to give you the connectors needed to hook up to a DMX receiver/decoder.

Splicer: Bonds 2 strips strips together on the cut line of the tape.

6″ Splicer Cable: Links 2 strips together on the cut line with a 6″ cable in between. This is great for corners. (Pictured)
24″ Splicer Cable: Links 2 strips together on the cut line with a 24″ cable in between. This is great for jumping to a spot close by.
