These are a couple of gate handle insulators with buckles to give you the correct insulation to make a tape gateway.

One of the insulators has one buckle and one has two. The fence insulator with two buckles is for the 'hinge' end of the gateway and will hold the end of the fenceline on one side and the tape that makes up the gate on the other.

The insulator with one tape buckle holds the start of the continuing run of fencing tape and has the gate handle hook into the loop on the other side.

These ensure your tape remains flat at the gate and doesn't all bunch together which can be unsightly. If you already have the tape to make a gate and a tape gate handle spare then these are all you'll need to make an effective and clean & tidy gateway for your paddock.
