STRONGHOLD ATTACHMENT WITH BUTYL
INSTALLING STRONGHOLD ATTACHMENT WITH BUTYL BASE TO RAFTER:
Peel-off the release paper from the underside of the attachment and place
stronghold attachment with butyl over rafter location and align edge of mount
with horizontal chalk line. Secure mount with the two (2) provided rafter screws
in the rafter holes of the attachment.
Note:
Ensure to use drill extension or deep socket tool for installing rafter screws.
CAUTION
• To determine if the screw is engaging the rafter, there should be resistance
to driving the screw through the entire length. If the screws do not properly
engage the rafter, install the 4 additional deck screws.
• It is recommended to begin installation with the screws on the upslope side
of the attachment and continue installing the screws on the downslope side
of the attachment for best fit.
Do not over-torque the structural screw.
When proper torque is applied, the EPDM washer
should slightly expand out from the sides as shown in
the image.
WARNING
INSTALLING STRONGHOLD ATTACHMENT WITH BUTYL BASE TO DECK:
When installing the attachment to the decking instead of the rafter (direct-
to-deck), install 4 additional screws on the remaining screw holes on the
attachment
CAUTION
1. Allowable attachment spans may change for direct-to-deck applications.
2. Unirac recommended spans are only valid with Unirac supplied screws.
Note:
• Additional deck screws are NOT included in the KIT. Must be purchased
separately.
• Pre-stock with additional screws in case going direct-to-deck.
