System operation viewed from above: Our all new Ermetika interior double pocket door systems have a free delivery as standard, these pocket doors come with full fitting instructions and the door system allows you to slide the doors straight in to a cavity in a preformed wall aperture, the system incorporates a galvanised steel cassette section and a track set with all fittings, soft close is also included. The door may be supplied with full decoration but no decor is included to the cassette system parts or its frame, check each door as you browse for the exact details. See our "Dimensions PDF" for all sizes but use as a guide only. The Ermetika pockets are available in two standard widths for a finished wall thickness of either 100mm or 125mm. Email [email protected] to receive a quote for any special sizes. The idea is to build the pocket to the same thickness as the studwork - 75mm (3") or 100mm (4") - which are the two standard studwork sizes generally in use, so that you can directly continue the standard 12.5mm plasterboard over the pocket providing the finished wall thickness of either 100mm (4") or 125mm (5"). Further layers of plasterboard can be added to increase the overall wall thickness, but other joinery work may be required. The inner door cavity (where the door slides in to the cassette pocket) is therefore 54mm or 79mm. Size limitations apply for the following items - Soft Close, Self Close and Simultaneous Openers - please refer to the individual accessory description. The Easy stop AB twin dual soft closer/opener, all other accessories for pocket doors including flush door handles can be purchased separately. Please Note: If the Simultaneous Opener is purchased, the AB Soft Closer will not be included as the two are not compatible with each other. However, another suitable type of soft closer will be provided. Doors will require a routered channel to be created in the bottom of each door to accommodate the supplied track guides. The double pocket door frame must be concealed with your own wall and architraves when installing. Note: These are two individual doors put together as two pairs and as such we cannot guarantee a perfect colour match.
