Most waterproof strips come in a square silicone plastic sleeve. When you cut one for resizing purposes it is messy and time consuming to get out the silicone glue and fill in the end of the open strip. These small silicone end pieces fit perfectly over the end of the strip and prevent any leakage without making a silicone mess. They come solid ended, needing only a small bit of silicone on the inside then they can be pushed onto the end of the strip and forgotten about. If the strips are to be moved about, to be further worked, on we put a small piece of blue tape over the end until the silicone is cured. For the same price are the above end-pieces but with 4 holes just the size you need for the gauge wire on RGB strips.

P.S. I will not charge you $1.00 for each item. $1 should ship several and only if you order a lot will you see any more than 1 dollar of freight. I do not make money on freight
