  • Bayliss Mk 7 Hydraulicheck Unit

    Bayliss Mk 7 Hydraulicheck Unit

    The addition of a small hydraulic damper which we have called 'hydraulicheck' to the Mk7 Autovent, creates an autovent suitable for use in severe weather conditions.

    It only allows the vent to be opened slowly but it can shut quickly. Whilst the Mk7 Triple Spring model offers an adequate degree of protection in most cases, lightweight vents can suffer wind damage in severe conditions. The solution is the hydraulicheck fitting, advisable in areas where severe conditions are encountered. Dimensions and lifting capacity are identical to the Mk7 standard unit. Supplied with satin anodised finish
