Introduction

Brickwork courses accept standard Type X cavitrays. However, different course sizes are sometimes encountered and a range of gable abutment multicourse cavitrays are available to accommodate different coursing heights. Multicourse cavitrays are based on the design of the Type X. They are proportioned to a accept a variety of walling materials and dimensions. Examples include reconstructed, faced, natural and concrete masonry, in course heights of 100mm, 125mm, 150mm, 175mm, 200mm, 225mm. The cavitray upstands are hinged to suit cavity widths from 50mm up to and including 160mm. The tray base dimensions are suitable for masonry skins of thickness up to 125mm, beyond which special fabricated trays are available to suit all depths.
