The Ragni R129SG mortar gauging trowel is a compact masonry trowel designed for measuring, mixing and applying small quantities of plaster or mortar, particularly where space is tight. With a 7" (180mm) carbon steel blade and a comfortable soft-grip handle, it’s a practical choice for bricklayers and tradespeople who want control and comfort on smaller mixes and touch-up work.
Also referred to as the R129SG gauging trowel, it’s shaped to work neatly in buckets and awkward areas, helping you lift and place mortar more accurately without the blade catching on the sides.
Note: Supplied as 1 gauging trowel (single piece).
