Metal end cap.
To suit 33.7mm tube.
A metal knock in plug which is difficult to remove once installed.
Ordered on line. I found it easy to navigate
Found what I needed, paid and it was delivered promptly. Would highly recommend and use again
Not quite what I expected. It looks like it is a "hammer into place" fitting. It isn't and needs something to keep it in place. In my case I used "epoxy steel". As a result a simple job became more complicated. But that apart (a rather serious issue). I guess it did what it said it would. I just feel the plastic knock in end cap would be better. Service was excellent though and I feel sure they would have taken it back if required to.
