DS12W2 20 300 600 - 88° AAMA 904.1: 1987 & BS 6375 PT.2 Note: Vent height/width is measured from rebate to rebate (not overall size or outer frame size) on conventional windows or glass size on structurally glazed windows e.g. curtain wall panels whichever is the greater dimension. For maximum vent height consult profile manufacturers for recommendations on requirements of system strength and sealing.
Note: For slim aluminium systems these vent sizes may need to be reduced on restricted hinges to comply with a maximum restricted opening of 100mm.
Note: The restricted opening gap with restricted hinges is controlled by the angle shown: the resulting gap will vary with profile and vent width.
