Section 2 - Mounting Ropewalker to Building Structure

Threaded Rod

Please Note: It is recommended that heavy items be hoisted up to the work area using appropriate machinery, i.e. hoisting lifts, block and tackle, etc.

When locating viewing surface and checking clearance for screen operation, remember surface is centered in the length of the case.

Regardless of mounting method used, the following points apply:

1. Screen should be lifted into position ONLY by end mounting brackets

or hoisting brackets. Keep case level by lifting both end plates at the

same time to prevent surface damage. Using more than one mounting

hole in each end plate ensures a much more stable installation. NEVER

attempt to lift screen along its length or in the middle.

2. Entire weight of unit MUST BE supported by end plates during

installation.

Please Note: DO NOT lift case at the center. Case leveling brackets

are ONLY used to reduce visible case deflection. Lift screen ONLY by

hoisting brackets. To ensure a safe installation, the entire weight of the

installed unit MUST BE supported by the mounting brackets.

for mounting surface. Installer must also ensure that structure is of adequate

strength. Supporting hardware

5. Entire bottom of case must be readily accessible after installation is complete.
