Prefix® concrete construction box for fixing to the reinforcement

The new Prefix® concrete construction boxes, in addition to the proven product features such as lateral installation clamps for fastening to the reinforcement, mounting clips for pre-fixing the items and marked wave profile for an exact and secure fit, now also have innovative conduit entries, insertion options in the rear part of the box as well as separators that can be broken out at a later date for connecting devices in combinations.

Spacers to the side formwork ensure full circulation of the concrete and allow exposed concrete installations in passage and edge areas
Suitable for 20 - 60 mm concrete covers
Innovative conduit entries with diameters of 25/32 mm and 20/25 mm, for quick fitting on the construction site
Insertion options up to 25 mm diameter on the rear base of the box
Easy manual assembly
Sturdy signal bristle and bold colouring for easy retrieval in the concrete surface
Large inlay and installation clearance
Easy installation of pre-wired installation accessories in multiple combinations using a bridge that can be broken off afterwards

Setting the concrete covers 20 - 40 mm / 40 - 60 mm

The assembly of the box for a concrete cover of 20 to 40 mm is carried out by installing the conduit entries at the bottom of the box.

This means that the conduit entries are located behind the first reinforcement layer and that time-consuming and destabilising reinforcement cuts are no longer necessary.

A concrete cover of 40 to 60 mm is also possible by simply turning the box upside down. For this purpose, the conduit entries must be arranged on the front part.

This means that the conduit entries are located in front of the first reinforcement layer and also remain usable without restrictions. The conduits are to be routed behind the reinforcement at the earliest opportunity.

Installation

Prepared working formwork with reinforcement from the opposing formwork side.

The conduit entries can easily be made with a pair of combination pliers.

The KAISER step drill (Art. No. 1284-32) can be used to precisely to produce the openings required at the back for conduits up to 25 mm in diameter.

With the KAISER universal opening cutter (Art. No. 1085-80), the required openings for cables or lines are made to fit exactly.

The bottom and front of the box are easily attached by hand. Note: pay attention to the concrete cover before sealing.

For multiple combinations, the Prefix® one-gang junction boxes can be combined at a standardised combination distance of 71 mm (DIN 49075).

The signal bristles on the front parts of the Prefix® articles ensure that the position of the Prefix® concrete construction boxes remains visible in the wall surface.
