ASSEMBLY AND INSTALLATION INSTRUCTIONS
THE SITE MUST BE LEVEL. YOU WILL HAVE MAJOR PROBLEMS IF IT IS NOT.
A VARIATION OF +/- 1” IS ACCEPTABLE.
LIFTING EQUIPMENT AND SCAFFOLDING IS NECESSARY TO ASSEMBLE FRAMES
AND ATTACH FABRIC
BECOME FAMILIAR WITH THE PARTS OF THE STRUCTURE. THERE ARE TWO SECTIONS EACH
OF THE BASE AND FRONT ARCH. THESE ARE 2-7/8” OD AND EACH HAS A MATING END
AND APPROPIRATE FITTINGS. THE BASE ARCH HAS STUBS AT APPROXIMATELY 5’-0” ON
CENTER THAT RECEIVE THE RIBS. THE FRONT ARCH HAS A CENTER STUB AND TABS TO
WHICH THE RIBS ARE ATTACHED.
THE RIBS ARE 2-3/8” OD AND ARE NUMBERED AS SHOWN ON THE PLAN VIEW.
1. SET THE CENTER BOTTOM ARCH SECTION IN THE PROPER LOCATION. THIS IS THE ONE
WITH THE STUBS GOING VERTICAL. ATTACH THE RIGHT AND LEFT SIDE OF THE BOTTOM
ARCH. DO NOT COMPLETELY TIGHTEN THE SET SCREWS AT THIS POINT. THE MAIN
ARCH MUST BE 50’-0” ACROSS. IF IT IS LESS OR MORE, ADJUST TO THIS WIDTH.
2. MARK THE POSITION OF THE TEN (10) ANCHOR FOOTINGS AND THE TWO (2) MAIN
FOOTINGS. MOVE THE BASE ARCH AWAY AND DIG THE FOOTINGS AS SHOWN ON THE
DRAWINGS. PLACE THE BASE ARCH BACK INTO POSITION AND TIGHTEN THE SET
SCREWS ONE FULL TURN PAST HAND TIGHT USING A WRENCH AND EXTENSION BAR.
STAKE THE BOTTOM ARCH INTO POSITION SO IT WILL NOT MOVE WHILE INSTALLING THE
FRONT ARCH.
3. ASSEMBLE THE FRONT ARCH ON THE GROUND IN FRONT OF THE BASE ARCH. THERE
ARE CENTER, RIGHT AND LEFT SECTIONS SIMILAR TO THE BASE. MAKE SURE THE STUB
AND TABS ALL FACE THE SAME DIRECTION. ie. GET RIGHT AND LEFT CORRECT.
TIGHTEN THE SET SCREWS WITH WRENCH AND EXTENSION BAR.
4. RAISE THE ASSEMBLED FRONT ARCH USING LIFTING EQUIPMENT. (THIS ARCH WEIGHS
APPROXIMATELY 350 lbs.) INSERT THE STUB FITTINGS OF THE FRONT ARCH INTO THE
ENDS OF THE BASE ARCH. MAKE SURE THE FITTINGS ARE SEATED AS FAR AS POSSIBLE.
TIGHTEN THE SET SCREWS ONE FULL TURN PAST HAND TIGHT USING A WRENCH AND
EXTENSION BAR. KEEP THE FRONT ARCH SUPPORTED IN A VERTICAL POSITION AS YOU
PROCEED WITH THE NEXT STEPS.
5. LOCATE THE NUMBERS ON THE RIBS AND MATCH THEM TO THE NUMBERS ON THE BASE
ARCH.
6. INSTALL THE CENTER RIB FIRST. IT WILL INSERT INTO THE BOTTOM AND FRONT ARCH
STUBS.
7. THE REMAINDER OF THE RIBS SLIP ONTO THE STUBS IN THE BASE ARCH AND USE THE
“SLIP” FITTING AT THE TOP ARCH TO ATTACH TO THE TABS. (SEE DRAWING)
8. INSTALL RIBS No. 5 NEXT. IT IS BEST TO PLACE THE NUT WELDED TO THE TOP OF THE RIB
TOWARDS THE CENTER OF THE ASSEMBLY. INSERT THE RIB ONTO THE STUB ON THE BASE
ARCH AND DO THE SAME WITH THE INSERT ON THE FRONT ARCH. YOU CAN MOVE THE
FRONT ARCH AS NECESSARY TO MAKE THIS CONNECTION. DO NOT TIGHTEN RIB SET
SCREWS UNTIL THE FRAME IS COMPLETE.
