11. Cut the internal trim to size and clip into position. This will centralise the assembly and assist before you screw fix the baypole to the frames. The trim should locate nearly on top of the windowboard or cill upstand. Before clipping into position you have an option to run a bead of sealant into the 'cups' along the edge of the extrusion for additional weather sealing.

12. When all frames are fixed into position you must then ensure that they are secured to the baypole. You should drill and fix at max. 250mm centres and this can be done with a screw through the frame or from outside through the 'V' grooves at the base of the aluminium legs projecting from the baypole. This fixing is especially important for load bearing situations. There should always be a minimum of three fixings. You can silicone around the jack detail at the base to ensure good weather performance. This needs to be done before fitting the external cover.

13. When all fixings are in position, cut the outer trim to size and clip it into position. You can also run a bead of sealant along the edges if you wish -- prior to fitting. Trims are supplied with protective tape, which should be removed within a day or two of the installation. Glaze and complete installation as normal.

BBA Accredited Loadbearing Calculations

The Window Widgets Variable Angle Baypole system has been BBA Approved (Report No. 2631) and can provide loadbearing calculations should you require. Below is a summary of the baypoles capabilities.

Window Widgets Variable Angle Baypole, Part No. 482054.

Note: Above table shows values of maximum permissible imposed loads on baypole at different lengths. Permissible stress detailed in BPF W 362/1 : Feb 2001 Aluminium Grade 6063 T6. Calculations based on lateral support from adjacent frame in the 'in line' frame direction. Frames must be screw fixed to baypole at 250mm centres.
