This optional upper end cup can be mounted on the post to receive the gate in addition to the bottom end cup.
The tension bar acts as a turnbuckle and builds in gate adjustability to moderate long term sag and post movement problems. Fits into 50mm square tubing and can be adapted to use in Imperial tubing sizes.
Side rollers are an alternative top guide. Useful especially when arched tops or other architectural features do not easily accommodate horizontal U-channels in the design.
