Boom fitting alignment blocks, for 11 mm Ø boom spars, a pair of blocks.

A pair of identical alignment blocks, each shaped on four faces to hold the various boom fittings supplied in the SAILSetc boom kit with an 11 mm Ø round spar.

If you still prefer to use 11 mm Ø round tube then you will find this pair of blocks ideal for aligning the 101-110, 46-110, 48-110, 104-110 and 101G-110 fittings correctly with respect to each other.
