BASEBALL BACKSTOP
NOTE: SPECIFICATIONS ARE SUBJECT TO CHANGE
9. REPEAT THIS PROCEDURE ALTERNATING FROM RIGHT TO LEFT. CHECK AS YOU
PROCEED TO MAKE SURE THAT THE FRONT ARCH IS PLUMB. IT IS BEST TO HAVE THE
ARCH SLIGHTLY LAID BACK RATHER THAN LEANING TO THE FRONT. PLUMB IS IDEAL.
10. AFTER ALL RIBS ARE IN PLACE, MAKE SURE ALL THE JOINTS ARE SEATED ON ALL RIBS
AND ARCH CONNECTIONS. ALIGN EVERYTHING TO THE BEST OF YOUR ABILITY.
TIGHTEN THE SET SCREWS ON THE FRONT ARCH WITH A WRENCH AND EXTENSION BAR.
DON’T TIGHTEN THE SET SCREWS FOR THE RIBS YET.
11. INSTALL THE HORIZONTAL STIFFENERS APPROXIMATELY 5’-0” ABOVE GRADE. START
WITH THE SHORT ONES BETWEEN RIBS 4 AND 5. ATTACH THE BEGINNING END WITH A
BRACE BAND AND BOLT w/ NUT. THE INSIDE CONNECTION USES SPLIT BRACE BANDS
AND BOLT w/ NUT. DO NOT TIGHTEN BOLTS UNTIL ALL THE STIFFENERS ARE IN PLACE.
12. INSTALL THE ANCHOR BOLTS AND NUTS IN THE HOLES IN THE BOTTOM ARCH. THREAD
THE NUTS ONTO THE ANCHOR BOLTS UNTIL ONE THREAD IS SHOWING.
13. PLACE THE MAIN FOOTING ANCHORS IN THE FOOTING HOLES AND INSERT THEM INTO
THE OPEN ENDS OF THE FRONT ARCH. TIGHTEN THE SET SCREWS WITH A HAMMER AND
WRENCH.
14. POUR CONCRETE IN THE FOOTING HOLES. THE MAIN FOOTING HOLES SHOULD BE
POURED TO WITHIN 2” OF FINISHED GRADE. THE ANCHOR BOLT HOLES CAN BE
POURED UP TO FINISHED GRADE. WAIT AT LEAST 72 HOURS BEFORE ATTACHING THE
FABRIC.
15. NOW THE FUN BEGINS. THERE ARE TWO ROLLS OF FABRIC EACH AT 9 ga. 12’ X 50’.
LOCATE THE TENSION BARS AND TENSION BANDS AND OTHER MISCELLANEOUS
FENCING HARDWARE.
16. THE CIRCUMFRENCE AT THE BASE OF THE ARCH IS 60 ft. YOU WILL HAVE TO WEAVE 10
ft FROM ONE ROLL ONTO THE OTHER 50 ft ROLL TO GET THE FIRS COURSE. STAND THE
WIRE ON EDGE AND PLACE THE FABRIC SO IT IS CENTERED ON THE OUTSIDE OF THE
FRAME AND JUST ENOUGH ABOVE THE BOTTOM ARCH SO THE TENSION BARS CAN BE
INSTALLED. PUT TIE WIRES ON THE CENTER RIB AND THE FABRIC. STRECH THE FABRIC
AROUND THE BOTTOM AS BEST AS YOU CAN AND INSTALL THE TENSION BARS IN THE
BOTTOM AND ATTACH BARS TO TENSION BANDS.
17. WHEN THE BOTTOM COURSE IS SUFFICIENTLY TIGHT, INSTALL TENSION BARS AND BANDS
ON THE FRONT ARCH AND CUT THE EXCESS FABRIC OFF ON THE BIAS. THE BOTTOM OF
THIS COURSE WILL BE EASILY STRECHED AND THE TOP WILL NOT BE REAL TIGHT. IT WILL
REQUIRE A BIAS CUT ON THE TOP OF THE COURES WHERE IT MEETS THE FRONT ARCH.
IT DOESN’T GET EASIER THAN THIS.
18. PLACE THE REMAINDER OF THE FABRIC IN THE CENTER OF THE BACKSTOP LIKE ABOVE.
SLIDE IT UP THE BACKSTOP UNTIL IT IS CLOSE TO THE FRONT ARCH. THERE SHOULD BE
AMPLE OVERLAP OVER THE FIRST COURSE OF FABRIC. STRECH THIS COURSE AS BEST
YOU CAN AND HOG TIE THE OVERLAP TO THE BOTTOM COURSE. THIS COURSE WILL
HAVE TO BE BIAS CUT AT THE ENDS BEFORE THE TENSION BE INSTALLED.
19. TIE THE FABRIC TO THE RIBS USING TIE WIRE. CLEAN UP AND YOU ARE DONE.
