Designed for use with the G960 Telescopic Under Floor Void Ventilator.

Description

The G961 Vertical Extension Sleeve is designed for use with the G960 Telescopic Under Floor Void Ventilator.


Features and benefits:

  • Each extension sleeve enables a further two course brick adjustment vertically.
  • Alternatively, the sleeve can also be clipped to the base of the G960 to provide horizontal extension through larger cavities or wider internal blockwork: each unit extends the underfloor ventilator a further 150 mm vertically or 185 mm horizontally and additional units can be added to achieve ventilation over any number of courses.
  • The G961 should be used in conjunction with other Manthorpe products to provide a complete through wall ventilation system.
