LC70: How To Mount Lights Using Heavy Duty C Clamps

Introduction

The Rockville LC70 Heavy Duty Lighting C-Clamp is designed to securely mount PAR lights, gobo lights, moving heads, bar lights, and other effect lights onto a truss system. With a weight capacity of up to 70 pounds, it provides a universal fit for most truss-compatible lighting fixtures.

This guide will cover:

• Mounting a PAR light using the LC70 clamp
• Using two LC70 clamps for bar lights
• Ensuring a secure truss setup

What’s Included

• LC70 Lighting C-Clamp (newer models feature an optional fly nut)
• Mounting bolt and wing nut (pre-installed)
• *Compatible with various lighting fixtures and truss systems

Step 1: Identifying the Correct Mounting Hole

Before installing the clamp, locate the truss mounting hole on your lighting fixture:

• For PAR lights (e.g., RockPAR 50, Best PAR 60): The truss mounting hole is typically found on the dual bracket.
• For bar lights (e.g., Battery Strip 24): Mounting brackets on both ends of the light will have holes for attachment.

Step 2: Mounting a PAR Light with the LC70 Clamp

1. Remove the Bolt from the LC70 Clamp
   • Unscrew the pre-installed mounting bolt from the LC70 clamp.
2. Attach the Clamp to the PAR Light
   • Run the bolt through the mounting hole on the dual bracket of your light.
   • Screw the bolt back into the LC70 clamp, securing the light to the clamp.
   • For added security, tighten the fly nut onto the bolt.
3. Positioning the Wing Nut
   • The wing nut can be installed on the inside or outside of the clamp based on your setup preferences.
4. Attaching the Light to the Truss
   • Hook the C-clamp onto the truss bar at your desired location.
   • Tighten the screw knob on the clamp to secure the light to the truss.

✅ Your PAR light is now securely mounted on the truss!

Step 3: Mounting a Bar Light with Two LC70 Clamps

Some larger lighting fixtures, such as bar lights, require two clamps for even weight distribution.

1. Remove the Light’s Side Brackets
   • Unscrew the side brackets from the bar light.
2. Attach the LC70 Clamps to the Brackets
   • Remove the bolts from the clamps.
   • Run the bolts through the mounting holes on the bar light brackets.
   • Screw the bolts back into the LC70 clamps.
   • For extra security, tighten the fly nuts onto the bolts.
3. Reattach the Brackets to the Bar Light
   • Use the original screws to secure the brackets back onto the bar light.
4. Mount the Bar Light to the Truss
   • Hook both LC70 clamps onto the truss.
   • Tighten the knob screws on each clamp to securely fasten the light.

✅ Your bar light is now safely mounted on the truss!

Step 4: Ensuring a Secure Truss Setup

• Ensure Power Availability
  • If your light requires AC power, ensure that there is power access on the truss.
  • If using battery-powered lights (e.g., Battery Strip 24), no power outlet is needed.
• Double-Check Tightness
  • Before finalizing the setup, tighten all screws and fly nuts to prevent any movement.

✅ Your lighting setup is now complete and secure!
