Automatic flush bolt
OLDA 37 HZA

note. This product was previously called 37 HZ

Function:

Automatic, single action flush bolt for non spring-loaded bolting of passive door leaf in double doors.

Features:

OLDA 37 HZA is bolted and unbolted automatically and has a forend width of 18 mm.

Same dimensions as automatic flush bolt OLDA 34 HZA and semi-automatic flush bolt OLDA 35 HZS.

37 HZA has a bevelled bolt with backset 3-19 mm and cross section 15 x 17 mm. Its sloping strike edge facilitates easier opening of the passive door leaf, for example when forces (pre-load) apply on the door leaf in the moment of opening – by reducing friction between bolt and frame/sill or lock plate.

It also has an additional “hold close” function, which is desired in fire, gas, sound or climate proof doors etc.

To optimize the “hold close” function and aid in correct installation – so that the sloping edge of the bolt is bolted against the front edge in the frame/sill or lock plate – the additional accessory: Adjustable lock plate OLDA 19 HZ is recommended.

Manufactured in steel. Coating: electrozinc plating.

Usage:

To be recessed into doors of wood, steel or aluminium profiles without joint edges, both up and/or down in the edge of passive door leaves, also rebated.

Installation:

OLDA 37 HZA is fitted recessed in the edge of the door, either flush, with cut-out or without cut-out for the forend.

Fixed with four screws.

OLDA type 1 automatic flush bolt is fitted upper right and lower left in passive door leaf.
