|ALUMINIUM BI-FOLD DOOR RESTRICTOR
The restrictor is 500mm long and fits in the outer frame roller channel which is 19mm deep.
It is "hold-open" and by moving the restrictor laterally in the channel many angles of opening and "holding" are achievable (from under 90 degrees up to 130 degrees).
There is an infinitely adjustable friction adjustment by means of a "phillips" screw.
