Springs - Torsion -
Extensions and One Piece Door Springs - Winding Bars
Springs - Extension The Stretch of an extension spring
is ½ the door height. Example: 7' high door is 84" divided by 2 = 42" of
spring stretch. All springs are rated minimum 10,000 cycles. Spring wire to be
hard drawn. A led tempered MB #2 material. To determine right spring, count
coils. Measure outside diameter and length of spring at rest. We recommend you
replace both sides to get proper and even pull from both sides.

Torsion
Springs

Please call us after completing the
steps below to place your order.
- Count & Measure 20 Coils of Spring. This will give you
wire size.
- Measure (I.D.) Inside Diameter
- Follow Chart to wire size and inside diameter. The number in
the box is the cost per inch
- Measure length of broken or unwound spring. Must be unwound to
get current measurement (coils only. Not fittings) Multiply length x nubmers
box to get cost of spring. Standard torsion ends come with winding and
stationary cones installed. Special torsion springs ends are 850 each spring
extra.
- VERY IMPORTANT: determine L.H. Wind or R.H. Wind. Sorry, no
returns on Springs if you have 2 springs. We recommend you replace both spring.
They have a cycle life and the one not broken is not far behind the one that
broke. If from the inside looking out your springs are bolted together in the
center as a rule the spring on the left is R.H.Wound and the spring on the
right is L.H. wound- all new springs rated for a minimum of 10,000 cycle (a
cycle is one open and close)
