At the heart of the CUPLOCK system is its unique
node-point locking device. This enables up to four
horizontals to be loosely but safely connected to the
standard then locked into position with a single
hammer blow. The system uses no loose clips, bolts
or wedges.
The locking device is formed by fixed lower cups,
welded to the standards at 0.5m intervals, and
sliding upper cups which drop over the blade ends
of the horizontals and rotate to lock them firmly
into place giving a positive, rigid connection.
