--160mm wide x 107mm high\n\n--45\u00B0, 90\u00B0, and 135\u00B0 angled sides\n\n--Can be used with flat steel and, round and square tubing\n\n--On/off switch for accurate positioning and quick cleaning\n\n--13kg holding force against 5mm thick mild steel\n\nThese strong and compact magnets provide a fast and easy way to hold two pieces of steel together at 45\u00B0, 90\u00B0 or 135\u00B0 while they are welded, soldered and assembled. Every magnet has a mechanical switch \u2013 when turned off there is no external magnetism so they can be freely and accurately positioned then when turned on the magnets clamp in place. In addition, the switching mechanism allows the magnet to be quickly and easily cleaned, for when it is switched off any metal swarf can simply be wiped off. The strong clamping force makes these magnets ideal for flat pieces, round and square tubing.
