Cut 6 equal pieces of 3/16" diameter

(5 mm) line, each about 18" (45 cm)

long. Tie each one to a corner latch of

the reflector with a bowline knot as

shown. Locate the 3 corner holes

which include the 3 stamped arrows.

Group these three attachment lines

and tie to the hoisting halyard. This will

automatically place the reflector in the

“catch rain” position if all three corner

lines are the same length. Attach the 3

remaining support lines to a downhaul

halyard. Suspend the reflector vertical-

ly as high as possible.

Mounting Echomaster #152

The standard Echomaster #152 does not include a mounting system. The best way

to install this product is to assemble it around a backstay or make your own bridle

and hang from holes drilled in the corner latches.

6-Point Temporary  Mounting

For infrequent, temporary mounting, a

rope harness can be constructed as

shown here.

Slide the remaining half plate in place, as shown

(reverse this half plate if the corner latches do not

match).

Snap in place the three remaining corner latches that

secure the half plates.
