Butterfly
Mount Bolt-On style reflectors behind post bolts with the reflector's prongs pointed towards oncoming traffic. Tighten bolts securely over two prongs of the reflector deep into slot provided. Mount Glue-On style reflectors in "V" channel with Dapco adhesive #795A.
IBM
Apply Dapco adhesive #795A inside the channel of the IBM marker and press into place on the top of the steel I-Beam post.
Straight
Straights may be mounted directly to wooden guardrail support posts using two (2) 16 DG nails with (2) 3/16" (0.5 cm) washers in the factory drilled holes provided. If ordered with sheeting on one side only, make sure that sheeted side faces traffic.
FG427 and FG527
The FG427 and 527 may be mounted directly to wooden guardrail support posts using two (2) 16 DG nails with two (2) 3/16" (0.5 cm) washers in the factory drilled holes provided. Install with sheeted side facing traffic. |
Davidson's 795A Adhesive Instructions for Use
Ideal application temperature is 50 to 100 degrees F (10 to 37 degrees C). Apply adhesive 1/8" (0.3 cm) thick to base or mounting surface of reflector. Press reflector onto and apply firm hand pressure for five (5) seconds. Adhesive should squeeze up through the glue holes provided on Butterflys and IBMs for better mechanical bonding. (Insufficient pressure will not allow for proper bonding and may result in adhesive failure). After application, the bond strength increases and approaches the ultimate bond strength after 72 hours at 70 degrees F (20 degrees C). Reflectors are then ready for traffic. Dapco Adhesive #795A will adhere to most clean, dry and well unified surfaces. Contamination of application surfaces by moisture, metal scale, dirt or grease will inhibit bonding of adhesive and can result in adhesive failure.
Reflective Sheeting
Shall be of a specified grade and size affixed to the post by manufacturer. |
