3.0 Temporary Roof
Anchors
Miller temporary roof anchors are anchorage
connectors designed for roofing applications
and are to be used with complete Miller Roof
Systems.
The RA15-1, RA20-1, RA25-1, RA30-1 and
RA35-1 roof anchors may only be used as
temporary anchor points and must not be
used where permanent anchors are needed.
The RA15-1, RA20-1, RA25-1, RA30-1
and RA35-1 roof anchors are reusable
anchorage connectors designed to be
repositioned as work progresses, provided
that the roof anchor has not seen fall arrest
forces and has not been damaged in any
way (refer to the inspection section of
this manual). It is recommended that new
fasteners/hardware be used each time the
roof anchor is installed.
The RA15-1, RA20-1, RA25-1, RA30-1 and
RA35-1 roof anchors are for use by ONE
person only.
The RA15-1, RA20-1, RA25-1, RA30-1 and
RA35-1 roof anchors are for use by the
original installer only.
Anchor points must be capable of sup-
porting 5,000 lbs. (22.2kN) in the direction
permitted by the system while in use (or
provide a 2:1 safety factor).
3.1 RA15-1

Warnings and Limitations

• The RA15-1 roof anchor is designed for
roof-top installations on fully sheathed
roofs comprised of wood members (*see
other approved installation options below). Do
not install on unsupported roof structures
such as eaves or gable overhangs. Do not
install on facia boards.
• The RA15-1 roof anchor must be installed
at least 2 ft. (0.6m) from any roof edge.
• Due to the fatiguing of the screws, it is
recommended that eight (8) new #12,
2-½" (63.5mm) long, type A, zinc-plated,
steel pan head screws be used each time
the anchor is installed. Roof anchor must
10
be inspected before each installation.
• The RA15-1 roof anchor must be used in
conjunction with a shock absorber that
limits forces to 900 lbf. (4kN) or less.
• Maximum capacity is 310 lbs. (140.6kg),
including body weight, clothing and
tools.
Installation
1. Locate and mark solid roof members/support
structures (i.e., studs, joists, rafters, trusses,
etc.) under roof sheathing at the location
where the roof anchor will be installed.
2. Refer to Fig. 1 for proper setup.
3. Install the RA15-1 roof anchor with eight (8)
#12 2-½" (63.5mm) long screws (four on
each side).
WARNING
Use all eight (8) #12 2-½" (63.5mm) long
screws to attach the RA15-1 roof anchor.
All eight screws must pass through the
sheathing and into a support structure.
If this warning is not followed, the an-
chorage connection will be weakened
and serious injury or death could occur
in the event of a fall.
Attach to the D-ring only with a locking
snap hook, locking carabiner, or other
Honeywell-approved connector or con-
necting device.
*Installation Options
The RA15-1 roof anchor can be flattened and
installed on a flat area of the roof so long as
all eight (8) #12, 2-½" (63.5mm) long screws
pass through the sheathing and into a support
structure.
The RA 15-1 can also be flattened and installed
to a wall in a vertical orientation so long as all
eight (8) #12, 2-½" (63.5mm) long screws pass
through the sheathing and into a support struc-
ture.
NOTE: The RA15-1 can be mounted onto a
metal roof in applications where the metal
sheet is a minimum 20 gauge (0.036") thick-
ness. It can be used in the original shape or
flattened and must be installed with eight (8)
#12 TEK screws. These screws are self-drilling
(no pre-drilling required) and are not included
with the RA15-1 roof anchor. Each TEK screw
must completely penetrate into a structural
member (e.g., purlins of Z bar or C bar).
