Confined Space Fan And Blower Accessories

Allegro flat washers or plain washers increase the surface area to distribute the fastener's load while reducing heat and friction during the tightening process in blowers, fans and more. They can also be used as spacers and provide electrical insulation.

Allegro blower grills provide a protective barrier for the fan blades in industrial plastic blowers & standard blowers by deflecting debris and objects from being inserted into the blades. These grills also reduce the risk of injuries by preventing accidental contact with spinning blades. Choose from a wide range of these blower grills, available in diameters ranging from 8 to 20 inches.

Allegro manhole signs remind workers to follow proper confined space procedures meeting OSHA's confined space warning requirements. They are made of high impact polycarbonate and fit under the manhole cover. These manhole signs feature ventilation holes that allow air to pass through and water to drain in. The design offers ease of using instrument probes without having to remove the sign from its position under the manhole cover.
