Many greenhouses have no grooves to fit the Alliplugs into the corner so these adaptors simply push onto the corner bar creating a fixing for use with the Alliplugs.

Found similar problems as other reviewers in that they fell off when subjected to strain. Had to fit them first to the frame using Silicon Sealant. Once dry they stayed in place bar two, probably because I didn't clean the frame enough. Bit on the expensive side.
Not many in the bag for the money - ran out quite quickly and needed more. Difficult to attach to thick aluminium main struts, easier with intermediates but then cannot take much strain or they fall off. Mostly needed at ends and corners which is where there is pull strain on them. Not as effective as the Allispacers but necessary where there is no channel for fixing allispacer. Just be careful and it will be OK
