Acetal resin based (POM) technopolymer.
Ball
Glass-fibre reinforced polyamide based (PA) technopolymer, black colour, matte finish.
Mounting
Self-tapping screw Ø 4.8 mm. UNI 7981 B or M5 cylindrical head screw with hexagon socket DIN 912.
BPS ball-shaped door lock (ELESA patent) consists of a clamp to be fixed to a frame and a ball to be fixed to a door.
The clamp, in which the ball fixed to the closing door is inserted, is a mechanical stop device also to the door movement, thanks to its shape.
The screws, that fix the clamp and the ball respectively to the frame and to the door, are identical. Thus, making the assembly easier.
Under specific tests, the clamp showed constant performances formore than 20.000 cycles.
The ball-shaped door lock has been conceived for use with both shutter doors and sliding doors.
The minimum thickness for the profile suitable for use is 15 mm, while the distance between door and frame must be within 2.5 mm and 3.5 mm (fig.1).
BPS-SP: acetal based (POM) technopolymer spacers kit 5, 10, 15 mm (sold separately), black colour in order to compensate possible differences in width between frame and door.
