Springs Holmes Garage Door Springs. has been manufacturing garage door springs and hardware
since 1920. They manufacture a wide variety of sizes of torsion
springs, extension springs and garage door hardware for various
applications in the garage door industry. Their products are all
certified by the state of California and our one-piece springs all
feature containment wire according to California Building Code. All of
their one-piece and torsion springs are coated using the patented
ThermaDep process to keep your hands cleaner and help your springs last
longer
Measure
overhead clearance in your garage by measuring the distance from bottom
of header to top of ceiling at various points as shown at distance "D".
here in STEP 1. This includes pipes, rafters, garage door opener or any
other obstructions.
STEP 2
Select appropriate headroom hole from table 1 based on your measurement from step 1.
STEP 3
Measure door thickness from face of door to mounting surface of door angle.
STEP 4
Measure down from the bottom of the header 20 1/4", plus the thickness
of the door, SEE STEP 3. Now mark where measured on center for top
hole. Next measure 6 5/8" and mark on center. These marks will be where
you drill and mount your hardware master plate. Next measure down 48"
and mark on center for your anchor chain. Next drill 1/4" holes where
all marks where made. Optional safety braces can be installed from
master plate shoulder bolt hole, to jamb. SEE STEP 10. Now nail rubber
bumpers to bottom of header approximately 10" from each jamb.
(optional).
STEP 5
Next go ahead and mount hardware via the master plate, securely
to jambs using the provided 3/8" lag screws and oval washers. Hardware
needs to be positioned as shown in the STEP 5 illustration. Place two
3/8" thick shims on the floor across door opening about 12" from the
jambs. Now bring the door into the opening by fitting the top of the
door face behind header inside the garage. The bottom of the door
should also be resting on the shims and the top of the door should be
resting on the header. Make sure the door is in it's most upright
verticle position. It will be necessary to loosen the 3/8" carraige
bolts and nuts for the cantilever arms. Door gaps are normally 3/8" to
5/8" on each side. Gaps need to be as even and strait as possible.
Getting gaps even may be require raising or lowering the door by adding
and or removing bottom shims on either side. With door in the proper
position, Use the provided 5/16" X 2" lags to secure hardware door
angle to the door side rails. Hardware door angle needs to be strait up
and down with an equal distance from outter edges of the door. Now
tighten your cantilever arm bolts. Place door stops between door and
jamb and mark extension of door past jamb edge. When door is in the
raised position, fasten door stops with the provided 1 3/4" long drive
nails to the jamb face about 6" above the floor.
NOTE: STEP 11
STEP 6
After step 5 it's time to securely
attach the anchor chain to jambs using the provided 3/8" lag screws and
oval washers. Anchor chain needs to be positioned as shown in the STEP
6 illustration.
STEP 7
IMPORTANT Prop the door into the full open position. Make sure prop is secure.
STEP 8a
For
single springs, install "C" hook thru the chain. Install the other "C"
hook over the lower bushing on the kicker plate as shown in the
illustration.
Attached spring to lower hook. Apply the "L" plate and keeper ring
according to the illustration. Then stretch the spring to connect to
the upper "C" hook. Add "L" plate and keeper ring. As a rule 1" of
prestretch is required
for proper operation, with no more than 2" of prestretch. Repeat the
procedure on opposite jamb.
Tip: You can also mock up for 1" of prestretch before assembling plates and keeper rings.
STEP 8b
For
double springs, install "W" hook thru the chain. Install the other "W"
hook over the lower bushing on the kicker plate as shown in the
illustration.
Attached springs to lower hook. Apply the plate and keeper ring
according to the illustration. Then stretch the spring to connect to
the upper "W" hook. Add plate and keeper ring. As a rule 1" of
prestretch is required
for proper operation. Repeat the procedure on opposite jamb.
Tip: You can also mock up for 1" of prestretch before assembling plates and keeper rings.
STEP 9
Step 9 will usually apply to garage doors that are not
equipped with garage door openers. Todays Liftmaster garage openers
make a far better lock than the lock itself. As a matter of fact
Liftmaster openers utilized posilock electronics. This means that the
opener will automatically push the door closed in the event of an
attempted intrusion.
Another tip is that the pull rope shown in the illustration may swing
in front of the openers safety sensors, causing the door to reopen. It
is also recommended not to install a handle on garage doors being
lifted with a garage door opener.
STEP 10
BALANCE ADJUSTMENT (IF NECESSARY) A.) If door is hard to pull down, use extra shoulder bolt from master plate and insert in first empty hole above the bolt that is already in kicker plate. B.) If door is comes down to easily, use extra shoulder bolt from master plate and insert in first empty hole below the bolt that is already in kicker plate. C.) Put nut on newly inserted bolt. D.) Remove nut from original bolt. E.) Remove original bolt. F.) Repeat on opposite jamb. F.) Repeat the complete procedure as necessary.
NOTE:If it is difficult to insert bolt into new adjustment hole:
1.) Insert bolt as far as possible.
2.) Align kicker holes with holes on the master arm.
3.) Apply nut.
4.) Pull bolt through by tightening the nut with a 9/16" wrench.
CAUTION: ALWAYS MAKE ADJUSTMENT WHEN DOOR IS OPEN. MAKE SURE PROP IS SECURE. ( AS IN STEP 7).
STEP 11
If adjustments were successful in STEP 10, door should work
easily for 3/4 travel. To make the door work easily for 1/4 travel, adjust kicker assembly as shown in the circled diagram.
NOTE: STEP 5 was put in place in an attempt to avoid this last part of STEP 11.
If door rubs on one of the jamb sides, it will be necessary to adjust
one of the door angle plates. This can be obtained by shifting the door
angle plate, opposite of the rubbing side, away from the jamb.
The amount of required shift, depends on how bad the door is rubbing
the jambs.
The safest way to make this adjustment is to securely prop door up, remove springs and bring door back into closed position. It may only be required to
remove the springs on the side where the door angle plate will be adjusted.
Once door is operating properly, check all bolts, lags and fasteners to make sure they are secure.
