Always keep to the following recommendations: The L-shaped edge piece measuring 24 x 19 mm or 24 x 24 mm requires the bonding of a stiffening piece (chipboard, MDF) measuring 38 x 16 mm or 38 x 19 mm in section to replace the part of the frame removed (diagram ). We advise the use of PU compound glue for...
