Application

Designed to provide protection where a new horizontal roof abutment meets an existing wall but can be used to replace original or missing cavity trays.

Description

Manufactured from injection moulded polypropylene, the trays are available for horizontal brickwork details. The products are supplied with or without lead attachment.


Features and benefits:

  • Assessed by the British Board of Agrèment.
  • The refurbishment tray can also be used in new build, horizontal situations or in conjunction with the GW 295 Horizontal Tray.
  • Integral stop ends and a hook feature remove the need to overlap the trays, providing a total effective length of 450 mm.
  • A G950 Weep Vent or G951 Peep Weep must be used in conjunction with this tray.
  • The tray has a front mortar clip that can be removed at any time once the mortar has set leaving a 25 mm deep aperture into which the lead is inserted and secured with lead wedges.
  • The GW 294 Refurbishment tray can be supplied unleaded or with short, standard, or long lead, stapled and sealed to the tray.
