Twist-Lock(R) Devices Watertight Safety-Shroud(R) Twist-Lock(R) System Features and Benefits Catalog number and color-coded voltage rating are easily visible even when in use Closure cap is included for environmental seal when device is not in use Alignment arrows and lock and unlock symbols provide a visual indication that devices are properly connected One-piece, engineered thermoplastic housing is impact-resistant for heavy-duty industrial environments External keying provides quick mating of devices All screws are #10 multiple drive head Cord grip screw recess minimizes screwdriver slippage HBL2733SW Blades are recessed for protection against bending and breaking HBL2731SW One-step automatic Thermoplastic Elastomer (TPE) seal and engineered thermoplastic guard assure sealing when device is fully connected Note: Works with Mechanical Interlocks, see page B-39 for additional information. B-14 TPE Gland Seal Assorted glands accommodate a wide range of cord sizes from #16-3 Type SJ to #8-5 Type S, SO Spring-Loaded Cover One-step push-to-close spring-loaded cover with latch allows for fast opening and closing of lift cover. Result: environmental sealing is assured Panel or Box Mount Receptacles and Inlets * High impact, thermoplastic housing for heavy-duty industrial environments. * Catalog number and color-coded voltage rating are easily visible when in use. * Stainless Steel 302/304, #10 multiple drive head mounting screws provide corrosion resistance. * Mounting screw recesses minimize screwdriver slippage. * Lockout/tagout hole on inlets allow compliance to OSHA regulation 29 CFR 1910.147. * TPE closure cap provided with inlets for environmental seal when not in use. * Accepts all mating NEMA locking plugs and most connector bodies, allowing interchangeability with existing devices. Safety-Shroud * Virtually eliminates bent and broken plug blades, leading to longer equipment life. * Extends life of mating receptacles by eliminating damage caused by insertion of bent blades. * Extra protection for personnel by significantly reducing chance of inadvertent contact with blades when connecting or disconnecting energized receptacles and connector bodies. * Reduces exposure to arcing when connecting or disconnecting plugs under load. * Compliance with California Code of Regulations, Title 8, Article 51, subsection 2510.7(b), which requires shrouding for devices exceeding 300 volts. * Lockout/tagout hole allows compliance with OSHA regulation 29 CFR 1910.147. * Sealing gland and thermoplastic guard assure sealing when fully connected.
