Standard Tretight 1700L consists of the following parts:
- TOP Cushion 1700, where the width is 3500 mm, extension part 1700 mm, 7 ducts
- SIDE Cushions L (right and left), where the length is 3650 mm, closing distance 1000 mm, 5 ducts
TRETIGHT™ top cushion
The cushion is sewn together for maximum flexibility. The top cushion is constructed so that, when deflated, its curtain and a part of the cushion itself, is rolled onto the roller. The curtain is attached to the roller by a double sticking tape.
The retraction is achieved by means of a counter weight placed in the left hand side cushion.
The cushion has eyelets for optimal function and for drainage of condensed water, if necessary. It is also equipped with internal elastics for improved retraction.
The fitting of the cushion is simplified by the usage of C-profiles in which a rope, sewn into the cushion, is inserted.
The backside of the top cushion is equipped with 3 tongues with eyelets for simple fixation of the cushion. All, except one internal fabric, are made from coated fabric. The top cushion has two air ducts for distribution of air to the side cushions and a PVC pipe which is used to connect the fan.
TRETIGHT™ side cushions
The side cushions are sewn. The unique curved design of the side cushions gives an excellent sealing ability.
The retraction is as standard by elastic cords which are fitted to the cushion by means of snap-hooks for easy exchanging. On the upper part 4 holes are placed for lowering of friction between the top and the side cushions. The side cushions are fitted to the wall by means of C-profiles.
There is a corner cushion to improve the tightness at the lower end of the cushion.
The left-hand side cushion has a hatch for handling of the counter weight when installing the seal.
TRETIGHT™ top and side cushions are installed with the fitting items, which are chosen accordingly. Read more about the TRETIGHT™ fitting items.
TRETIGHT™ is CE-marked and its construction matches the requirements of the EU machinery and product safety directives.
