BOA Hose Grips Whip Sock from Lewis Mfg.Blow Out Arrest Hose Grip or BOA™ is a Wire Mesh Whip Sock manufactured by Lewis Mfg. BOA hose grip is used on high pressure hose to safely minimizes the dangerous high pressure whipping of a hose on blow out. Also, as a Bundle Keeper, BOA provides hose abrasion and wear protection near the hose coupler’s fitting, where needed the most. A hose grip’s construction is similar to a DLE grip but has much longer leads (15″) for easier and flexible installation. BOA is available in galvanized steel or aramid fibers.

Lewis Split Grips – both Rod and Lace Closing – are designed for all phases of suspension or pulling, where neither end of the conductor is available and “middle of the run” application of the grip is desired. Various head variations are available.
No, taping alone is not reliable enough. We recommend to Double Band and Tape ends of the grips. Please see our banding instructions for proper installation.

A bundling grip or bundle keeper is a grip used to keep several cables or umbilicals organized in one neat bundle. One of the major hazards at most worksites are the cables and hoses used during construction. The use of our bundling grips not only reduces this hazard greatly, but also provides a protective outer layer of steel mesh for the cables and or hoses to be installed. These grips can be ordered in several different lengths and sizes to fill your requirements precisely.
NO!  If a grip has broken or frayed strands, it should be removed from service and replaced immediately. This is an important safety concern.
Any grip can be used for pulling cable or rope (natural or synthetic) as long as the working load limit is not exceeded, and the grip is properly Banded AND Taped.

Rope compresses (decreases diameter) as it is pulled, so be aware that if the rope compresses to a diameter smaller than the grip minimum diameter range, the rope will slip.

We use aircraft grade steel cable to manufacture all of our standard wire mesh grips. Using a special process, we apply a UV resistant plastic coating to the steel cable while manufacturing the majority of our grips. The coating allows much easier handling, installation, and removal of the grips. The working strength difference between the coated and uncoated steel cable is minimal and with the large safety factor (3-1) that we incorporate in our grip designs, it becomes negligible.

Inspect swivel carefully before and after each use.

  • Check for cracks around the throat on both ends of the swivel, and on the body of the swivel. If cracks in the body of the swivel are apparent, or if the pins are bent, discard swivel immediately.
  • Make sure the swivel rotates freely and smoothly without any binding. The swivel stem should not be loose, with no up and down or lateral movement. Swivel should be smooth turning and snugly fitted together with no sloppiness in the operation. Do not use a damaged swivel.
  • Before making a pull, make sure swivel pins are tightened and mate up properly. If pins have stripped threads, replace immediately. Pins are available with standard slot grooves or with Allen wrench fittings.
  • Do not exceed the work load stenciled on every Lewis swivel. If you anticipate being within 10% of the work load during any pull, a larger swivel should be considered, especially if any shock loading might occur during the pull. If the work load is in question, please consult with the factory in Oklahoma City by calling Toll-Free 888-398-4719.
  • Do not pull any swivel around a bull wheel that has a smaller diameter than the length of the swivel. Doing so exposes the swivel to a side load, and can permanently damage your swivel. If you know a Ball Bearing swivel has been exposed to an unqualified side load, the swivel should be removed from service and replaced.
  • Lubricate all greasable swivels before and after each use. Make sure there is no debris in the swivel gap, that is, the area where rotation occurs between the swivel body and eye. The only substance that should be in the swivel gap is the grease that has been used to purge the swivel of contaminants. The specified grease for our swivels is Mystic JT-6 Multi Purpose Water Resistant Grease, but any high grade waterproof grease will suffice.
  • Do not expose the swivel to long durations of harsh and corrosive environments. After each use remove the swivel and the grip, clean & store them in a dry and protected location so that they are not exposed to harsh environments such as offshore drilling platforms or other salty, corrosive environments.

Non-Magnetic, No MagnetLewis Manufacturing’s Non-Magnetic Suspension Grips are constructed Tin Coated Bronze which is Non-Magnetic. Tin coated bronze is ideal for standard support applications under regular tension. Tin coated bronze is non-magnetic and has excellent corrosive resistance properties. These grips should be used in an environment that requires non-magnetic materials or corrosion resistance.

The Ouchless Lewis Grips are made of aramid fibers that do not have the metallic fraying as traditional steel wire mesh grips do thereby eliminating the chance of being injured from metallic strands that have been abraded. The Aramid fiber can be used in essentially all grip configurations. Ouchless grips can also be used when a metallic grip is unsuitable, such as when pulling into an energized environment.

Aramid fiberOuchless Grips Aramid Fibers Logo is a generic name for a class of heat-resistant and strong synthetic fibers. They are used in aerospace and military applications, for ballistic rated body armor fabric and ballistic composites, for example. They are fibers in which the chain molecules are highly oriented along the fiber axis, so the strength of the chemical bond can be exploited. For example, Kevlar® made by DuPont is a registered trade mark brand of aramid fiber.

We manufacture Ouchless Lewis Grips™ made of aramid fiber strands that can be used in essentially all grip configurations specifically, the grips can also be used when a metallic grip is unsuitable, such as when pulling into an energized environment. However when used around coastal areas or in corrosive environments the Stainless Steel option is still superior.

Cable Measure CircumferenceCross-1

YES, you will need the outside diameter in inches of each cable in the bundle to figure the outside diameter of the complete bundle, and thus select the proper grip from the application chart in our catalog.

Yes, we believe cable should always be suspended in the conduit by some form of suspension grip.

The primary purpose of a suspension grip is to relieve pressure on the pot-head connection. This can be accomplished by using either our standard U-Bail type grip or the more popular Conduit Riser grip. The U-bail series is attached to the pole by using a J-Hook which screws into the pole. The conduit riser grip allows the cable to be suspended by placing the weight on the pole mounted conduit system. The ring sits atop the edge of the conduit, and is fitted to specific sizes of conduit. The mesh size is then figured to ensure a proper fit. These “ring” grips also provide a barrier to varmints and prevent them from becoming trapped within the conduit system, possibly causing a fault, fire, or electrocution.

The difference between the overhead and underground grips

In general, overhead grips have higher working loads to accommodate the higher tensions primary overhead cable pulls require. Many grips are interchangeable and can be used for both purposes; however most customers prefer to keep their overhead and underground grips separate. The underground grips may become caked with mud and other contaminants which are unfavorable to overhead operations as well as inside conduit pulls.

Both! You should band your grips with two bands; one approximately ½ to 1” from the end of the grip and the other approximately 4-6 inches above the first. The bands should be installed snugly with no looseness or sliding. To ensure a smooth profile, place several wraps of electricians tape over the steel bands. We strongly recommend using the Band-It® banding system from Lewis Manufacturing. It provides a high quality secure band.

Grips should be replaced when they show signs of wear such as, but not limited to, frayed strands, broken strands, missing copper end tabs, and rust. In the grand scheme of things grips are a very inexpensive tool, and should be replaced when showing early signs of wear. Never use a grip that is broken and/or frayed. Always check your grip for any defects before and after each use.

Heat-Sealed is a process of joining the rubberized canvas at the seams using heating process instead of sewing. The heat-sealed method provides a much better and stronger seam.

No It Can Not!

A grip, once frayed or damaged in any way should be removed from service immediately.
