INTRODUCTION
The Profab 3000 series 'Loft Hatch' is designed to provide access between into 50mm wide timber truss/ joisted plaster/plasterboard ceilings, where access to the loft space is required.
DESCRIPTION
COMPOSITION & MANUFACTURE
The metal frame holds a flush metal door through adjustable hinges to one side. The door is held closed with either concealed push catches (PC) or a security key lock (SL). The door opens down towards the user and is removable during installation or if damage occurs. Panels with simulated dry wall beaded frames (BF) are jointed/skim-plastered and then decorated on site to match the colour/texture of the adjacent finish. Picture frame (PF) panels are finished semi-gloss white so require no finishing after installation. A 2mm gap is maintained between the door and frame through the adjustable hinges.

OTHER OPTIONS
The 3000 series 'Loft Hatch' is designed and manufactured to provide quick and easy installation with a discreet quality appearance when finished. Only limited modifications are available with this product due to its design. However, Profab do manufacture a wide range of access panels. Our manufacturing flexibility provides for bespoke designs, alternative sizes, locks and paint colours. Discussions with Profab should take place at the earliest opportunity when specifications are being considered.
INSTALLATION
Apertures should ideally be formed between the timber trusses/joists if at 600mm centres, with cross-trimmers fixed to suit selected panel. Suitable frame packing should be used at fixing points to ensure frame remains square. Typical fixing details are shown on this data sheet. Loft Ladder installations are possible with this product and Profab should be contacted for further advice before specification or installation.
OPERATION
Where the panel is fitted with concealed touch catches and is installed into a standard height residential ceiling, the door can be opened from floor level with the supplied operating pole. Suitable steps should be used to access the more secure, key operated option. (Additional operating poles and keys are available from Profab).
