HEYCO Strain Reliefs

• Made of zinc-plated steel.
• Used together with our Strain Relief Bushings.
• For situations where the panel is too flexible to support UL's 35# strain relief pull-out test.
• OR for situations where the panel is thin relative to the strain relief's locking slot. The backup washer eliminates "play".
• OR can be used to contain the strain relief bushing in U-slot openings.
• Quick Specs below don't apply.

• Made of zinc-plated steel.
• Converts trade size knock-out holes to diameters suitable for strain relief bushings.
• Allows for standardization of panel design since various strain relief bushings sizes can be adapted to one panel hole size.
• Allows for the mounting of strain relief bushings into unusually thick panel.
• Adapters mount into 1/2" knock-outs (7/8" or 22.2 mm nominal diameter).

• Closes unused strain relief mounting holes or other chorded or Double "D" holes punched or molded with two opposing flats.
• Convex, matte finish head tapers to a thin edge.
• Locks firmly in panels up to 1/8" (3.2 mm) thick.
• Quick and easy installation.
• Use our rectangular plug #1890 to fill unneeded Lockit® Strain Relief mounting holes.

• Punches Strain Relief mounting holes.
• Double "D" configuration protects your strain relief and cable assembly from the forces of twist.
• Quick and easy operation.
• Unique design prevents metal distortion during punching operation.
• Allows for the punching of mild steel, aluminum, fiberglass, and plastic.
• Wrench operated.

• A button lock, flexibly connected to the bushing, mounts into a hole alongside the bushing.
• This button lock secures the bushing to the panel during cable removal or replacement.

US Patent No. 5052643

• Captive screw cannot be removed from body during cable removal or replacement. (The screw forces the locking flap against the cable.)
• Reinforcing ribs provide extra strength.
• Nylon USR-400 series parts may help you comply with IEC Publication #335, CEE #10 and #11; VDE #0720, #0730, and others.
• Protects your cable against forces of pull, push, twist, and FLEX; prevents use of larger-than-intended cord diameter.
• Easy panel installation : fingertip pressure locks bushing into 7/8" (22.2 mm) holes with wall thickness up ...
  
  

• Part No. 3791, T-bar available in black only.
• During cable removal or replacement, the T-Bar prevents complete removal of the strain relief bushing from the panel, reducing the risk of losing the bushing.
• Not for use in any mounting hole greater than .625" (16.0 mm) in diameter.
• Snap T-Bar onto the strain relief bushing strap (linking body to key piece), then feed it into the chassis mounting hole.

• The Heyco UL Knot is quick and easy to secure on any SPT-2 wire.
• It is cost effective. No cutting or tools needed as with metal clamp type strain reliefs. There is no risk of repetitive motion strain or injury.
• Recognized (far exceeds UL's 35# pull-out test).
• UL Approved for use with SPT-2 Wire.

• Assembly friendly. Independent of insertion into the panel, Lockit Strain Reliefs self-lock onto the cable. Thus, they may be preassembled offline for final assembly at a later time or remote location, for lower installed cost.
• Large mounting hole design allows passage of plugs or bulky assemblies during Lockit installation.
• Lockit Strain Reliefs hold so well they pass the UL pull-out test requirements with or without panel support.
• They protect the lifeline of your electric/electronic products by absorbing the forces of push and pull that may be exerted on the flexible power cord. And, their rectangular design eliminates the possibility of part ...
