Anyone who works on the maintenance of electrical panels, industrial cabinets, or metal doors is familiar with universal cam locks: they\u2019re affordable, versatile, and easy to replace. The universal square-key lock<\/strong> (part no. 165642) belongs to this family, but stands out due to the shape of the required mounting hole\u2014square rather than round\u2014which is designed to better resist attempts to rotate or forcibly remove the lock body. <\/p>\n

When cut open, the body reveals a circle with a diameter of 16.2 mm on which four flat surfaces are milled at 90\u00b0 intervals (14.2 mm between each flat surface): the resulting shape provides more anti-rotation contact surfaces than the standard double-D-shaped hole, making the lock more stable during opening and closing. The term \u201csquare\u201d here refers only to the shape of the body\u2014it should not be confused with square- or triangular-shaped socket key locks for meters and small panels, which are entirely different products. <\/p>\n

It opens with a nickel-plated, serrated, non-reversible brass key that operates a 5-plate-cylinder barrel: the same security mechanism found in the most widely used OMR plate-cylinder cam locks, but in a body with a different profile.<\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n\n
