Aco Threshold Drain

[SamHLM]

Im currently installing these Aco Threshold drains and I can't figure out how the end cap connects? It just seems far too small, has anyone else experienced this?

Looks the narrower door threshold end cap, try searching without using the term threshold. Toolstation do them.

The cap just slots over the end of the channel, assuming you have matching parts. This pic is for the end cap wth an outlet but your end cap should look a bit like this:

So I stupidly had non Aco branded threshold drain and these were specifically Aco ones. Fingers crossed I've ordered the right one now, thanks for your help anyway
