Product Identity

This product is a pair of 150lb garage door extension springs finished in black electrophoretic coating. Each spring measures 25 inches at rest and stretches to 67 inches, designed for residential doors up to 7 ft tall. The set includes non-slip gloves and installation instructions for immediate fitting.

Build Integration

The double-loop ends connect directly to existing eye-bolts and pulleys, replacing open-loop or clip-style ends without extra hardware. ASTM-A228 heat-treated steel coils rated for 16000 cycles and 300-hour salt-spray resistance eliminate routine lubrication and free the installer from periodic tension adjustments.

Buyer Fit

Suits homeowners replacing worn springs on standard 7 ft doors who want a corrosion-resistant, maintenance-free kit with included safety gloves. Not suited for doors taller than 7 ft, heavier door configurations exceeding the 150lb rating, or installations requiring single-loop or clip-type end fittings.

Highlights

  • Rated for 16000 open-close cycles minimum
  • Heat-treated ASTM-A228 steel ensures long-lasting durability
  • 300-hour salt-spray test confirms corrosion resistance
  • Double-loop ends provide stronger eye-bolt connection
  • Includes gloves and instructions for immediate installation

Questions about this item

How many open-and-close cycles are the 150lb springs rated for before fatigue?

The springs are tested to a minimum of 16000 cycles, with each cycle counted as one full opening and closing of the garage door.

Do the springs generate noticeable heat or noise during daily operation?

The extension springs operate mechanically without a motor, so they produce no electrical heat and only minimal metal-on-metal sound during normal door movement.

What tools or hardware must I already have to install these double-loop springs?

You will need compatible eye-bolts and pulleys that accept double-loop ends, plus standard hand tools such as wrenches and locking pliers for tensioning.
