  • Description & Key Features

    Product Description

    Manthorpe's range of abutment cavity trays can be supplied with short, standard or long lead fixed and sealed to the tray in either code 4 or code 5 (code 5 is a special order).

    Short lead flashings are for use with lead soakers and secret gutter upstands at the abutment and have a vertical drop of 75mm.

    Long lead is used for dressing down over and onto the roof covering at the abutment and is long enough to dress into the profile of the covering if required, it is most commonly used with contoured roof coverings. When ordered on a stepped system tray, long lead refers to a vertical drop of 75mm with an additional 150mm to dress over the roof covering. On a horizontal system tray however, long lead offers an overall flashing length of 300mm (75mm vertical drop, 225mm to dress over the covering).

    Standard lead with an overall flashing length of 150mm (75mm vertical drop, 75mm over the covering) is also available on horizontal trays for use when dressing down onto various shallow and flat profile roof coverings in lower exposure areas.

    Code 4 lead is for use in general details in normal exposure areas, for severe exposure areas it is recommended to use code 5 lead which offers better weather protection and has an additional 50mm coverage on the long lead option.

    Traditional Lead trays are available in all the available cavity tray options below:
