Confined Space Fan And Blower Accessories

Allegro machine screws are ideal for fastening metal parts securely together in various types of machinery or construction applications. They convert torque (rotational force) to linear force and are one of the six classical simple machines. These metal screws clamp machine parts together, either in conjunction with a nut or when one of the parts has a threaded hole.

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.

Allegro tap bolts or hex head bolts feature hex headed bolts with a fully threaded shank for use in a variety of projects including attaching motors to machinery, marine and exterior woodworking applications. They are inserted through drilled holes in assembled parts and tightened by torquing a nut They can also be mated with an internally threaded (tapped) hole and tightened by torquing the bolt's head. Tap bolts have high tensile strength for withstanding harsh or corrosive environments.

Allegro lock washers or external tooth lock washers are a special type of washers that create tension so that the bolt doesn't loosen or come out of its installed position. Lock washers comes in semi-coiled shape or have teeth protruding away from their outer diameter. They prevent the rotational movement of the installed bolts by locking them in place. These washers unlike nuts, do not get loose when exposed to vibrations.

Allegro elbows are used as replacements for sampling pumps to sample air for the presence of airborne contaminants. Selected models feature threaded ends for minimising chances of leakage during operation.

Allegro power cords connect confined space fans & blowers to a power source. They either have a moulded plug at one end to connect to an electrical outlet or a bare wire at the end to wire the devices. Selected models have strain relief cords to protect the cords from breaking due to bends and other stresses.

Allegro explosion-proof extension cords come with a 20 Amp connector and attachment. These temperature resistant adaptable cords have a temperature scope of - 40 Degrees F to 221 Degrees F and offer superior abrasion resistance. Both the plug and receptacle have CSA affirmations for Class I Division 1 and 2 Groups B, C, and D; Class II, Division 1 and 2 Groups F and G. Choose from a range of these Allegro black, 50 inch, explosion-proof extension cords, available in 125VAC and 220VAC voltage options.

Allegro hex nuts are designed for fastening components together in Deluxe dewatering pumps used for removing / extracting water in mining & basement drainages. Their 304 stainless steel construction prevents highly abrasive environments from damaging / wearing the fastener.
