SECTION 11 6733
CLIMBING WALLS
PART 1 - GENERAL
1.1 RELATED DOCUMENTS
A. Drawings and general provisions of the Contract, including General and Supplementary
Conditions and Division 01 Specification Sections, apply to this Section.
1.2 SUMMARY
A. Section includes custom climbing walls and accessories.
B. Related Requirements:
1. Section 01 8113 “Sustainable Design Requirements” for general requirements and
procedures for compliance with certain USGBC LEED prerequisites and credits.
2. Section 11 6623 "Gymnasium Equipment" for protective surfacing around climbing walls.
1.3 DEFINITIONS
A. Artificial Climbing Wall: Sports equipment exclusively designed and originally built for climbing.
Artificial climbing walls may be designed and used for lead climbing, top rope climbing, and
bouldering.
B. Seamless textured substrate: The finished surface of the described climbing wall system. The
surface is a hand troweled two-coat cementitious surface that is applied over an expanded
metal lath substrate which is mechanically attached to a plywood surface. The plywood surface
is mechanically attached to a metal frame that is anchored to a custom steel structure.
C. Route: Climbable surface approximately five feet wide that extends vertically from the base of
the wall. The number of potential routes on a climbing wall is normally determined by the width
of the wall at a height of five feet from its base.
D. Anchor Point: Used to belay climbers during their ascent or to lower them during their descent.
E. Top Rope Climbing: A style of climbing where the climber is safeguarded by a rope that passes
through a belay anchor at the top of the climb. The climber always remains below the anchor
as they climb.
F. Lead Climbing: A style of climbing where the climber is safeguarded by a rope that is passed
through an anchor point as the climber progresses up the artificial climbing wall. The climber
must clip the rope into each anchor point as they progress up the artificial climbing wall so that
they are safeguarded from ground falls while ascending to the final anchor points at the top.
Typically lead climbing anchor points are placed at spacing of 4 feet vertically to prevent a long
fall.
G. Top Rope Belay Anchor: Located just above the top of the wall, this anchor system consists of
two fixed ring type anchors or a welded bar mounted to a plate extending 4 to 6 inches out from

the face of the climbing surface. Climbing rope is secured by running through both rings or
around the bar one and a half times.
H. Rappel Station: Usually placed part way up a taller artificial climbing wall or at a ledge used for
teaching or rappelling. Used to stop and belay a partner up so that they continue climbing from
that point. A belay station usually consists of at least two distinct anchor points, linked by a
chain (or webbing) in a "V" with a ring (or locking carabiner) in its interior part.
I. Automatic Belay: The Automatic Belay is a mechanical controlled descent device designed
specifically for the climbing wall and climbing gym industry. The Auto Belay provides a hands
free belay for the climber, thereby eliminating the need for an additional climber or attendant to
serve as belayer. As the climber ascends, the slack rope or cable is pulled taut. Once at the top,
or whenever the climber lets go of the wall, the device gently lowers them to the ground.
