Rectangular guards cover exposed shafts, couplings, and other rotating components mounted on flat or rectangular equipment surfaces, where a round bearing cover wouldn’t match the underlying geometry. Available in flanged and unflanged, and guard or backplate configurations, a rectangular machine guard mounts using bolt holes positioned around its perimeter, matching common industrial frame and housing layouts. Because rectangular guards are typically manufactured in standard stock sizes as well as custom dimensions, MRO teams can usually find a close match to an existing footprint without commissioning a fully custom guard. 3BG Supply Co. stocks rectangular guards in steel, aluminum, and polycarbonate materials, alongside our standard guards and tapered guards lines within our broader machine guards selection.

FAQs
What is a rectangular guard used for?
A rectangular guard covers exposed shafts, couplings, or other rotating components mounted on a flat or rectangular equipment surface, protecting workers from contact and keeping contaminants away from the mechanism. Its rectangular shape matches equipment footprints where a round cover wouldn't fit properly.
What's the difference between a flanged and unflanged rectangular guard?
A flanged rectangular guard includes a mounting lip around its edge for bolting to the equipment surface, while an unflanged version typically mounts more directly or is used as part of a layered guarding system. The right choice depends on your existing mounting surface and bolt access.
Are rectangular guards available in custom sizes?
Yes — rectangular guards are commonly available in standard stock dimensions as well as custom sizes, since equipment footprints vary considerably between manufacturers. Providing exact length, width, and mounting hole measurements helps ensure a proper custom fit.
What materials are rectangular guards made from?
Rectangular guards are typically made from steel, aluminum, or polycarbonate, depending on the level of impact resistance, weight, and visibility needed for the application. Polycarbonate options allow visual inspection of the guarded component without removing the guard.
How do rectangular guards differ from round bearing covers?
Rectangular guards are designed for flat or rectangular equipment surfaces and mounting patterns, while round bearing covers are shaped to match circular bearing housings. Choosing between them comes down to the geometry of the component you need to guard.
