Windows
Our AG210 windows are approved by Conservation Officers for their slimline frame and traditional styling. They include the following features…
Multipoint locking
All of our windows are fitted with a key locked handle which drives our multipoint locking system, providing increased security over single point handles.
Traditional weld on hinges and stays
AG210 windows are standardly fitted with fully working welded hinges in traditional extended or pear drop designs, and supplied with a peg stay for greater authenticity. A range of sliding stays with butterfly or round ‘taps’ are an optional extra.
Window restrictors
An ideal child safety device, we can fit window restrictors. Designed to limit opening of a window to 100mm, it can be manually released to facilitate the full opening of the window, automatically re-engaging the restricted position on closing the window.
Concealed friction hinges
Where clean neat lines are preferred, the AG210 can be fitted with concealed friction hinges, offering a range of opening and easi-clean options maintaining traditional slim frames with a modern look.
AG210 Doors & Screens
Our AG210 doors are designed to recreate the distinctive styling of traditional steel doors. Our doors can be supplied with single or double handles, traditional lock boxes and face bolts, or lever lift locking.
