Specifications - Imperial Vent Size and Weight Chart - STORM Hinges

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 and widths not stated, consult profile manufacturers for recommendations on requirements of system strength and sealing. 

Note: *Vents of 220 lb or higher must be fitted with S7280 Cam adjustment devices which are optional on lighter vents. 

Note: Separate restrictors (SR8 or SR16 pair), vent holding devices or an operating mechanism maybe required to hold large vents in a selected ventilation position against variable wind pressure. 

Note: As with all types of friction hinges friction cannot be provided until the slider moves, therefore when limiting the opening top hung vents to angles of 10° or less, additional separate device(s) will be required on top hung vents to enable them to remain in a selected ventilation position. 

Note: Above sizes/weights also apply to BX (Sterling Offset series)

Note: For loose rivet versions, used with opening devices please contact Securistyle for advice on maximum sizes and weights.
