Use your project drawings. Progressive provides the industry’s best and
most comprehensive project drawings, which will tell you everything from
exact locations to what clamps to use. If the drawing is to scale, the scale
can always be found at the bottom of the drawing.

How to Use This Manual
This manual covers installation of all Progressive backstops, and is
designed to be used in conjunction with project drawings.
Project drawings provided by Progressive show clamp numbers and posi-
tions for each backstop on a job. Begin at step 1, the top, and work your way
down, following assembly instructions for clamps provided for each specific
installation.
6
Mark superstructure dimensions on floor using a chalk line, then use a
plumb bob to transfer those marks to the roof. Use blue chalk color (won’t
stain floor).
7
After snapping chalk lines, place clear plastic throws on the floor. This will
protect the floor, while allowing you to see the chalk lines.
8
All dimensions are referenced from Face of Bank, Center Line of Court,
Center Line of Backstop Main Stem, or Center of Clamp. Refer to project
drawings for dimensions. Remember to account for offset dimensions
(Center of Clamp to Edge of Clamp) when marking beams for clamp place-
ment, and
especially when installing bent stem models
.
9
Prior to assembly, distribute parts to the correct backstop locations.
Backstops may differ in model number or dimension; make sure you have
the proper parts for each backstop location.
10
All Progressive Gymnasium Equipment is supplied with Grade 5 hardware.
Clamps are designed to be installed with the nuts and bolts “tight.”
Progressive would consider tight to be torques between 40 ft-lbs and
60 ft-lbs.
Please Note: When assembling T-Frames, place Top-of-T on two over-
turned five gallon buckets; place bottom of stem on casters or a small
wheeled cart.
These instructions are meant as a guide only. They do not bind Progressive
Sports Construction Group in any way and do not imply any responsibility of
Progressive for improper installation or faulty workmanship at the jobsite.

Caution
1
When laying out parts, be careful not to place them where they may be in
the way of scaffolding, lifts or working areas.
2
To reduce the risk of injury to those working below, take only tools
required for attaching Truss to roof.
3
Before beginning assembly, locate and identify all parts using hardware
list and project drawings.
4
Backstops must be installed level and plumb.
5
Do not operate folding backstops unless safety belt has been installed (if
safety belt is part of job).
6
Make sure power is disconnected before wiring winches.
7
Do not install damaged or defective parts.
Installation Tips
1
Whenever possible, install bolts with heads toward the floor (threads
pointed up), or with heads toward the front (threads facing rear of
backstop).
2
Assemble backstop (Ceiling-Suspended only) on the floor, then hoist into
attachment position. There are several options for hoisting.
Use extreme caution.
3
For tube attachments, loosely bolt one side of clamp together, hold tube in
place, swing bottom of clamp around, add second bolt and finish bolting
(see Fig. G-1).
Caution: Progressive is not responsible for roof strength. Do not
install Truss if roof is not strong enough to bear stress loads required
for backstop.
Caution: Progressive is not responsible for wall strength. Do
not install wall pads if wall is not strong enough to bear stress loads
required for backstop. Attachment method to be determined by project
architect/engineer. Attachment hardware provided by others.
