Headbox System of 51

1 / The chain cover can be installed on the right or left of the box, depending on the hand of the chain and it is screwed to the three points of the aluminium box with flat head screws 3 x 25.

2 / The counterweight of the Night and Day system has two aluminium profiles. The end caps fit firmly and are screwed to the aluminium with flat head screws 3 x 10.

3 / The hidden aluminium counterweight has the advantage of being loaded with steel bars inside if necessary. The end caps fit firmly.

The Headbox of 51 x 51 uses the 26 m/m chain system.

We can not only manufacture conventional blinds with the box, we can also manufacture Day and Night blinds. To this end we have the A and B locations where the P.V.C weldable is lodged.

When manufacturing a Night and Day blind we can produce two different effects:

If we lodge the P.V.C weldable in the position A, the fixed part of the blind will be behind the drop of the fabric and we can see the pulling up and down of the blind.

If we lodge the P.V.C weldable in the position B, the fixed part of the blind will be front of the drop of the fabric, hiding the pulling up and down of the fabric.
