I am looking for a supplier to purchase 2 x square bay pole jacks, preferably with 90 degree spreader plates built into the base. They are to fit 2 x L shaped bays (1st floor & ground floor). The inner aluminium re-enforcing of the corner posts are approximately 55mm x 55mm outer and 50mm x 50mm inner dimensions. The window profiles are Synerjy by Synseal. I am a joiner and intend fitting the windows myself. The front bay windows are in my own home. I can get the windows registered under Fenca on completion. As the bays are load bearing I am looking at using bay pole Jacks to support the load on the corners of both upper and lower bays. (The window frames have been re-enforced during manufacture). Can any of you window fitters please advise where is the best place to get the correct size bay pole jacks from please? Also any advice on any pitfalls to watch out for while fitting the bays would be gratefully appreciated.

Kind Regards
