Oil-Tempered Torsion Spring for Precise Garage Door Counterbalance
This THP Torsion Spring features a .218-inch wire gauge, 1.75-inch inside diameter (ID), and 25-inch coil length. Manufactured from ASTM 229 Class II High-Carbon Steel and oil-tempered for a minimum of 10,000 cycles, it outlasts galvanized springs that lose tension over time.
The .218 wire gauge is engineered for medium-weight doors too heavy for .207 but too light for .225 springs. Installing the exact match protects your garage door opener from gear failure by ensuring the door feels virtually weightless during operation.
How to Confirm This Is the Correct Torsion Spring Size
Do not guess. A difference of one wire size makes a door dangerous. Confirm: (1) Count 20 coils of .218 wire = approx. 4 3/8". If 4 1/8" you need .207; if 4 1/2" you need .225. (2) Winding cone must read "175" or "1-3/4". (3) Red cone = Right Wind (left side), Black cone = Left Wind (right side).
