Dori Block 51mm x 50mm Double Pinned Aluminium Brick Gauge

A double pinned aluminium brick gauge Dori block used for setting out brickwork and making up a 51mm x 50mm brick gauge. Built for straightforward site use, it gives a simple, practical way to work from common profile sizes without overcomplicating the job.

Used in bricklaying and general masonry work, this type of block helps when setting out courses accurately and keeping gauge work consistent on site. It suits tradespeople moving between different jobs, as well as anyone working from steel or aluminium profiles already in use. The double pinned layout also makes it easier to use left or right handed, which is useful when working quickly or adjusting your position around a wall or corner.

Made from aluminium, the block stays manageable in the hand while keeping the format simple and job-focused. Compatibility with 40mm, 50mm and 50.8mm steel or aluminium profiles means it can cover common site setups without needing separate blocks for each one. The 51mm x 50mm gauge format is suited to brickwork setting-out tasks where consistent marking and repeat use matter. For regular site work, that flexibility can help avoid swapping between different blocks when profile sizes change. The uncomplicated design also makes it easy to keep with other bricklaying tools and ready for day-to-day use.
