Back check TBR series

with adjustable damping force

Characteristics

  • Dampen doors when opening speed is too fast
  • Damping force can be adjusted exactly to the requirements directly on site
  • Particularly suitable for high loads or for applications in which the load cannot be determined accurately enough
  • Optionally available with integrated mechanical stop
  • Can be used in combination with an overhead door closer
  • The opening angle at which the damping starts can be adjusted by reducing the oil filling quantity

Models and accessories

  • Selection criteria: Depending on door weight, opening angle and installation situation, different models are available in two series with different diameters (10-23 and 14-28). Details can be found under the ‘Selection criteria’ tab.
  • Components included: By default, back checks are always supplied with an eyelet, both on piston rod and cylinder
  • Accessories-sets: Information on the various accessories-sets can be found under the ‘Standard-sets’ tab

Of course we also produce back checks with other dimensions if none of the standard types suit your application. Our technical advisory service will gladly assist you in choosing and determining the mounting positions (anfrage@dictator.de).

These two tables show an overview about the available sets. Each consists of a back check with the appropriate fixing accessories. For detailed information about the fixing accessories, please see Installation accessories. The dimensions of the fixing eyelets can also be found there.

Of course any back check can be furnished with the corresponding fixing accessories. For the back checks in AISI 316 not all mounting brackets are available. Should you have any questions, please, contact us.

General installation instructions

When installing the back check, it is essential to ensure that they are firmly and securely fastened to the door and frame, as very high forces can occur here. If the door or frame is made of thin-walled steel or similar, we recommend the use of mounting plates.

It must be also ensured that the piston rod is not completely retracted when the door is closed. It should still protrude 10 mm from the cylinder so that the door can be opened without any problem.

Back check with integrated stop: When determining the correct mounting position, it should be taken into account that the locking position is approximately 3º before the complete opening, i.e. before the piston rod is completely extended.

  • The damping force of the adjustable TBR back checks can be adjusted continuously and at any time.
  • For this purpose, pull out the piston rod of the models without mechanical stop as far as possible (1) and then turn it carefully while still pulling (2).
  • With the models with mechanical stop you have to push the piston rod as far as possible into the cylinder (1) and then turn it carefully (2).Adjustment:
  • Turning clockwise: more damping
  • Turning anticlockwise: less damping
