Installation instructions Thonic tc-ue

Thonic tc-ue surface mounted

  • Function: Thonic tc-ue is a traditional inspection hatch fitted with a surface mounted frame. Installation is very quick as the fastening plates are pre-assembled and knocked out with a hammer behind the first drywall board or between the drywall boards when installed in double drywall. The hatch comes in standard sizes from 150 x 150 to 600 x 600 mm. Thonic tc-ue is delivered white painted, NCS S 0502-Y. For sizes up to 300 x 300 mm, the hatch has a self-fixing lock. For sizes larger than 300 x 300 mm, the hatch is fitted with a countersunk drive lock. When installing on ceilings, we recommend that the hatch be fitted with a hinged tc-gj and drive lock tc-ml. Thonic tc-ue can be customised with other sizes, in any colour or with optional accessories such as a range of hinges, lock models, etc.
