Replacement springs

Replacement springs

Pick the application, measure your old spring, and match it against real stock rows. If nothing matches, the builder makes one to your numbers.

• Garage door torsion and extension replacement springsTorsion: measure 20 coils and divide by 20 for wire size, read the inside diameter, and measure length unwound; note wind direction. Extension: measure length hook to hook with the door open, plus wire and outside diameter.
• Trampoline replacement springsMeasure the spring hook to hook at rest, then the coil outside diameter and wire thickness. Count springs on the frame so you order the whole set.
• Screen and storm door replacement springsMeasure length between hook ends with the door closed, then outside diameter and wire thickness. A longer spring at the same diameter closes more gently.
• Lawn mower and small engine replacement springsRemove the spring and lay it on a ruler: measure free length, outside diameter and wire thickness, and note hook or leg shape before ordering.
• Gate and door closer replacement springsMeasure the spring length at rest between its ends, the outside diameter and the wire thickness. Note how it mounts: hooks, loops or a barrel housing.
• Motorcycle and powersports replacement springsMeasure free length, outside diameter and wire thickness, and note end shape. For stands and levers record hook distance at rest.
• Automotive replacement springsRemove the spring and measure free length, outside diameter and wire thickness; note hook or leg style and its position on the vehicle.
• Furniture replacement springsMeasure length hook to hook at rest, outside diameter and wire thickness. Count the springs in the frame so the whole set is replaced together.
• Battery contact replacement springsMeasure the spring height uncompressed, its largest diameter and the base plate size, and note whether it is conical or a flat contact.
• Assortment and small spring replacement springsKits contain several sizes. Measure the spring you need and compare it with the sizes the kit lists before ordering.
• Die replacement springsRead the hole diameter and free length in millimeters, and the load class from the color or marking. Die springs follow ISO 10243 sizes.
