This handy device is used to connect two 1.5" or 2" polytapes together or can be used for the end of a run. You can use this to hook a gate handle if you want to make your own gates. These tape ends are a must if you are using 1.5" or 2" tape. This is one of those items that you need to get a "couple of extra" just in case you find out that you need them. Comes in packs of 3.
