Wire Strain Relief/ Cord Strain Relief & Connector Strain Relief Solutions
Plastic/ PVC Solutions for Standard and Custom Applications
Our company supplies off the shelf and custom wire strain relief/ cord strain relief & connector strain
relief products, such as bushings, fittings, connector boots, cable grommets, and strain reliefs. We manufacture plastic and rubber wire management products for improved flex and strain relief at the
cable exit point for panels, black box applications and enclosures.
We provide hundreds of strain relief and cable grommet designs for cable assemblies. Our strain reliefs have a
unique modular design for maximum versatility and utilization across a potential wide range of over mold designs. This leads to significant cost cuts for our customers.
Cable Grommets and wire strain reliefs are available in four shapes; round, oval, square or rectangular. These
grommets may either be molded directly onto the cable or be discreet slip-on style boots.
Our Wire Strain Relief system utilizes a modular tooling design, thus providing maximum flexibility in interchangeable
sections, and ultimately a lower strain relief cost. Furthermore, standard cable strain relief lead times are reduced to weeks rather than months.
We use a configuration manager to provide over 20,000 semi-custom grommets, which are ready to mold, and are
typically available for shipment in 1-2 weeks after order. Alternatively the typical lead-time for a custom cable strain
relief is 3 - 4 weeks ARO. PVC is the standard molding material, but we can also provide Santoprene or Polyurethane
Ordering Information: Weprovide for more than 20,000 combinations of semi-custom molded grommets, either as
discrete slip on units, or molded directly onto a cable. If you do not find what you are looking for, please contact us for
further information on custom order. PVC is the standard molding material, but we can also provide Santoprene or Polyurethane
Cable Strain Relief Basics
Do I Need a Cable Strain Relief?
A Cable Strain Relief provides extra protection to cables and wiring harnesses, at connection points on
equipment. Cable strain reliefs extend cord life and reinforce the cord connection to your equipment.
Strain Reliefs with Flex Reliefs
Depending on your application, you may wish to specify a cable strain relief with integral flex support. The flex
support protects the cord from stress that is applied perpendicular to the axis of its entry into the equipment.
Pull Tests for Strain Reliefs
After installing the cable and the strain relief, the product should be able to pass a pull test. UL calls for stringent
pull tests, which consists of a weight fixed to the cable for one minute. After the one-minute is over, a visual
inspection is performed to determine if the cable has slipped from the strain relief.
Dome Style Strain Reliefs
Dome style strain reliefs, named because of their domed shape, are designed
to protect the wire entering the equipment. They help to secure the wire connection to the equipment, and provide longer life to the cord by preventing
it from rubbing against a rough or sharp edge where the cord passes through the equipment panel
Flex Strain Reliefs
Flex style strain reliefs are named because they offer flexible bend protection to the cord entering the
equipment. They are designed to eliminate the possibility of the cord kinking at the point where it enters the equipment.
90° Angled Strain Reliefs
Our 90° angled strain reliefs can be used with both a flex or dome nut. They add strength and support to the cord and minimize wire strain in a bending application.
