The Air Tool Reel provides an air hose and ratchet mechanism that
allows a tool to stay suspended. To disengage the ratchet and
enable the hose to retract, simply pull lightly on the hose. The reel
comes with a standard 6.5 foot (2.0 m) 3/8” hose. Additional hose
can be added in 3.28, 6.56, and 9.84 foot (1, 2, and 3 meter)
lengths. The reel also is made with a fall prevention device. In the
case the spring breaks, the device prevents the tool from falling and
becoming damaged. Available as both a hood mount (ATR-5) and
as a wall mount (ATR-5-1).
• Hook, wall, or ceiling mount.
• Tension adjustment is easy and precise.
• High impact ABS case and a forged swivel hook.

Features and Benefits
Advantages of Using an ENDO Spring Balancer:
ENDO Spring Balancers are a valuable addition to your
assembly line. They support heavy tools with cable tension
equal to the weight of the suspended tools, which makes
them seem virtually "weightless". As the tool is repositioned
the balancer extends or retracts the support cable to follow
the tool's movements. Constant tension on the cable is
accomplished with a spring motor and a tapered drum.
The assembler has the flexibility to reposition the tool,
while experiencing comfortable operation and less fatigue.
Similar to a Balancer is the Retractor, which does not
have a tapered drum. The tension on the cable increases
as the cable is extended
• Suspend tools in assembly lines or other work areas
• Help the assembler with repetitive tasks such as
   installing fasteners: screws, nuts, bolts, etc.
• Hold fixtures, tools, welding guns, and similar
• Improves efficiency and diminishes worker fatigue
• Stabilizes tool positioning and contributes to work
• Contributes to a safer working environment
• Keeps fixtures, tools, and welding guns off of the floor
   and clean.
• Eliminates the need to separately power the balancer
Application Guidelines
• Size the balancer to carry the total weight to be balanced - tool plus all accessories - and stroke (maximum to
   minimum height) required.
• Size to the upper end of the capacity range of the balancer when possible.
• Always attach secondary support cable(s) to the eyelet provided for additional safety.
• Balancers are normally hung vertically and the rope is pulled out vertically. To prevent the rope from wearing on the
   guide, the rope should not be pulled out at an angle to the balancer body. The balancer can also be mounted
   horizontally, however a pulley system must be employed to guide the rope straight out of the balancer then down to
   the tool. Again, care must be taken to prevent the rope from wearing on the guide. A trolley and rail system can be
   used to help the balancer adjust to changing angles.
• If multiple balancers are used in close together, install them at staggered heights to keep them from hitting each other
• The spring tension is factory preset to the mid-range of the rated capacity. To adjust the tension turn the worm gear
   or spindle clockwise to increase the tension and counterclockwise to decrease the tension.
