• Slide the Header insert into the stringer body

• Line up the holes

• Using the access hole at the end of the stringer body

& (6) 1/2"-13 x 11/2" Flange Bolts, (6) 1/2" Washers &

(6) 1/2" Nylon Lock Nuts, secure the insert into place

Side Panel of Stringer Body cut away to show detail

• Place all tread brackets on the stringer

• Insert locator pins to hold the tread brackets in place

• Fasten the 1/2" x 31/2" Hex Lag through the middle

slotted hole in the header plate to hold the stringer

in place

• Lift the stringer into place, lining up the hole

• We recommend using either a pulley system or a Come

Along Winch and brace material to hold the stringer in

place while fastening

• Predrill with a 3/8" drill bit

Straight Stringer Installation Steps (Continued)

• Ensure the tread is level on the tread bracket both front

to back and left to right

• Using the 5/16" x 21/2" RSS Screws, attach the tread to

the tread bracket

• During this step, alternate sides of the bracket when

fastening screws. This will prevent the tread from

pulling unevenly

• Place a single tread on to one of the tread brackets

about half-way up the stringer

• Thread the 1/2" x 1" flange bolts through the tread

bracket and into the stringer in the marked order, so

they are finger tight

• Torque to 70 lb-ft

• Insert the threaded studs into each hole

• Thread the 1/2" x 8" hex head bolts into place, so they

are finger tight

• Predrill through the header plate holes with a 3/8" drill bit

• At this point, predrill all your header plate holes using

a 1/2" bit

• If not level left to right, shim the header plate to adjust

• If not level front to back, shim the footer plate to adjust

• Cut the excess shim away

on the nosing mounting block

• Using a 3/16" bit, drill four evenly spaced holes along the

center line

• Using the 11/16" Forstner bit, drill in the same spots 3/8"

deep. This will counter sink the mounting screws

• Do not mount at this point

• Secure the optional Tread Bracket Covers, using the

provided 3M Dual Lock fasteners to attach the cover
