For Point of Purchase (POP) Display and Merchandising design, our three enclosed reel product lines (spring retrievers) make excellent choices for product security and/or product placement. We offer three styles of spring-loaded cable retracting reels, all of which are made with plastic cases.Miniature Enclosed Reel seriesRetriever seriesEnclosed Reel seriesAn enclosed reel is simply an open reel within a closed envelope or package. With an enclosed reel, the single function available is linear pull from the cable, which in the retracted position, is enclosed in the housing. The enclosed reels are available in a range of loads and extensions. The enclosed reel can be installed by putting it in a cavity, by means of a mounting plate that can be supplied, or in some cases, by using the through hole.Spring reel load, extension characteristics, and capacities vary with the spring used. With a given maximum extension, the load may be varied by changing the width. Reels are provided with attached cable, equal in length to the maximum available cable extension. Other cable lengths are available as required.Spring reel applications typically are those requiring long deflection in proportion to the load. They include such uses as door closers, counter balances, cord retractors, retail display theft prevention, tool balancers, or holders.
Note Note
We can customized reels upon request. Reel cases are made of either Metal (MR). The load and deflection (travel) are determined by size and spring thickness. The nominal load in measured at 80% of the total available deflection.

John Evansâ manufactures "open style" construction spring reels, also known as arbor reels. In an open reel, the cable is exposed, wrapped around the exterior circumference of the reel, and contained between two flanges & under load generated by the internal spring. Spring reels provide lift assistance to any assembly that must be raised, reducing the "felt" weight and having the ability to make adjustments to pre-load and maximum travel. They can precisely counterbalance loads from less than one pound to over 50 pounds.Examples of applications include:Counterbalancing of an elevator door, reducing the force required to close and maintain the closed condition of doors on each floor.Reducing the energy required to lift a roll-up door on delivery trucks, or to lessen the effort to open and close the door/stairs on executive jets and other aerospace applications.Enabling adjustments to height, pre-load and maximum travel for various tools and fixtures in ergonomically designed workstations.Medical equipment designers can utilize spring reels to counterbalance a movable mechanism or monitor stand in the operating theater as well as hose, cable, tubing management around or within medical electronics cabinets.Open reels are available in a variety of sizes:Diameters range from 1.64" to 6.0"Widths vary from 0.49" to 1.63"From 1.64" through 5.09" dia. available with plastic casesFrom 3.38" through 6.00" dia. available with metal casesAll models of both metal and plastic are available with either a square hole Acetal plastic arbor (with a 0.320" square hole for mounting with a 5/16" carriage bolt) for a "bolt-thru" or a threaded stud for a "bolt-on" installation. Stainless steel & galvanized steel cable with ring terminals for outer end attachment as well as arbor style configurations can be found in our Spring Reels Specifications Table & Open Spring Reel Notes.
