STEP 5: Painting the BILCO basement door:
BILCO Basement doors are supplied in either a red oxide primer or powder coat paint nish. If your door has a powder coat nish, no additional
nishing is required.
IM PO RTANT: Doors supplied with a primer nish must be painted within forty-ve (45) days of installation. BILCO requires the use of
an exterior alkyd base enamel. For best results, carefully follow the directions on the paint label and apply one thin coat of paint followed
by a second coat on both the exterior and interior primed steel surfaces of the door. Two quarts should be sufcient to coat the entire door.
Application of paints that are not alkyd based may void product warranty.
STEP 4: Gas Spring Installation:
With the BILCO basement door frame
solidly anchored, the gas spring opera
-
tors can now be installed. Attach lower
spring bracket to side piece stiffener
(on side of stiffener facing top step)
using (2) 5/16” x 1/2” bolts and lock
nuts as shown in Figure 4B. Attach
ball fasteners supplied in bag with
gas springs to lower spring bracket
and upper spring bracket as shown in
Figure #4A & B. Note: Make sure the
that ball portion of the fastener is
facing towards the house on both
brackets. With fasteners securely
tightened and door in the open posi-
tion, push gas spring onto lower ball
fastener as shown in Figure 4B until
you hear it snap into place. Position
and snap other end of gas spring onto
upper spring bracket shown in Figure
4A to complete spring installation.
