The Monument 2355M OMAT® Soldering Mat measures 300mm x 300mm, making it the largest size in the range and ideal for working on extensive pipework installations or where additional coverage is required around multiple joints. This generous size provides maximum protection to surrounding surfaces, particularly useful when soldering in tight spaces with flammable materials nearby. This patented cut-out mat is specifically designed for soldering copper pipes from 15-22mm in diameter. Its unique shape with overlap creates a tight, secure fit that wraps completely around the pipe, offering superior protection compared to conventional flat soldering mats. Constructed from woven glass fabric, it's completely asbestos-free and stitched all around for long-lasting durability.
