Each Redpoint Auto Belay Descender needs be
connected to an anchorage so as to prevent accidental disengagement or rollout
of the auto belay unit. There are many
types of installation hardware that are suitable for attaching the auto
belay unit - choosing the right material and systems is very importnat. The information that follows discusses a
connection systems that are
in general use and readily available. Most auto belay installations can be accomplished using these hardware elements
individually or combined as described below. All installation methods and hardware must meet the minimum requirements set
forth within the below instructions. Never use installation methods and hardware other than those recommended by the manufacturer or qualified engineer. All
auto belay installation hardware and the specific mounting location must
meet a minimum strength requirement of 4,400 lbs (19.6 kN) in the direction of anticipated loading.
EYE BOLTS
Eye bolts must be manufactured from a weldless forged alloy steel construction with a shoulder pattern, threaded shank, washer and nut.
The length of shank and diameter of the threaded cross-section shall be appropriate for the specific installation. The
breaking strength of each eye bolt must be a minimum 4,400 lbs (19.6 kN) for any loading direction anticipated by
use of the auto belay system. Verify that
intermediate anchorage connectors (carabiner, rapid link, snap hook or shackle) are compatible to prevent accidental disengagement
(“rollout”) of the auto belay unit. Proper selection and installation must be performed under the supervision of a qualified person. Always install the eye bolt such that the anticipated loading direction is
within 30° of the eyebolt axis. Never install the auto belay unit to an eyebolt mounted
horizontally. Eye bolts without a nut are not recommended
because they can work loose. Verify that the nut is properly torqued
against the washer and will not loosen over time, and that the
structure to which the eyebolt is mounted is
capable of supporting 4,400 lbs (19.6 kN) in the direction of any anticipated
loading.
ANCHOR CONNECTOR STRAP
MSA model 505282 nylon or 505298 polyester 5 ft (1.5m)
anchorage connector straps can be used as an anchorage
connector for the auto belay devices when wrapped around a suitable anchorage such as a beam or pipe. The strap has a sewn loop at one end and a steel D-ring on the other end. If the beam around which the strap is installed
has sharp edges, padding between the beam and strap should be installed.
D-PLATE ANCHORAGE CONNECTOR
The D-plate is a permanent, user installed, over-head anchorage connector that can be welded or bolted to a suitable
beam or girder. We recommend models 506632 (zinc plated steel) and 506633 (stainless steel)
for connecting the auto belay units. Contact us for
information and separate user instructions for the selection and use of this equipment.
 
CARABINERS
Carabiner model 506308 is used as an anchorage connector when linked between the
Auto Belay Installation Handle and an appropriate anchorage connector such as a
beam or pipe, or through an Eyebolt or D-ring of the anchorage connector strap. This
carabiner has a throat opening of 2 inches (5.1 cm) and a minimum breaking strength
of 5,000 lbs. Always verify that the carabiner is loaded along its major axis, with the gate
closed and locked. Loading the carabiner in any other manner will reduce its strength
to the point where it may fail. Contact us for information and separate user
instructions for the selection and use of this equipment.

The Auto Belay Unit cannot be installed for use on structures higher than 39ft.
