I have a used a-frame for sale, it has come off the sea scouts RIB as it doesn't fit in the shed!
Will post at cost, not sure who'll ship it though...
Width over all 1.4m
Height over all 1.7m
(If you cut the flare box holders off the width would be 1.25m)
The inner width at the mounting plates is 600mm
Although this is stainless, the flare boxes which are welded to it are not. They need removing or painting.
Price: £100, this will go into scout funds.
I probably have a pair flare boxes, £10 each (this will also go into scout funds as I will donate them to the cause)
