Tube and Truss Compatibility

EVT100S Mini Square Truss and Verified 18–20 mm Tube Applications.

The EVT20C-ALC is designed for tubing measuring from 18 mm to 20 mm outside diameter. Compatibility requires verifying the actual tube size, clamp seating, attachment method, and allowable load of the complete installation.

EVT100S Compatibility
Designed for EVT100S Mini Square Aluminum Truss using compatible small-diameter tubing.
18 mm Tube Compatibility
Fits verified tubing with an 18 mm / 0.70 in outside diameter.
20 mm Tube Compatibility
Fits verified tubing with a 20 mm / 0.78 in outside diameter.
Other Tube Applications
Use only when the actual outside diameter falls within the documented range and the complete installation is approved.

Installation Sequence

Position and Tighten the Clamp in A Controlled Five-Step Process.

01 — Release the Wing Nut
Turn the wing nut counterclockwise to release the bolt and open the collar.
02 — Place the Clamp
Position the EVT20C-ALC on the compatible truss, tube, or pipe and close the collar.
03 — Reinstall the Bolt
Return the bolt to position with the washer and wing nut above the collar.
04 — Confirm Final Position
Verify the clamp is located in the correct area before tightening.
05 — Tighten the Wing Nut
Turn the wing nut clockwise until the clamp is securely seated without damaging the tube.
06 — Add Secondary Safety
Use an independently rated safety cable whenever required for the attached fixture or installation.

Inspection and Maintenance

Inspect Before Every Use. Remove Damaged Clamps from Service.

Clamp Body
Check the aluminum collar for cracks, deformation, impact damage, or excessive wear.
Stainless Hardware
Inspect the M6 bolt, spring lock washer, wing nut, and threads for damage or corrosion.
Tube Contact Surfaces
Keep the clamping surfaces clean and free from debris that could interfere with full seating.
Closure Operation
Confirm the collar opens, closes, and tightens smoothly before installation.
Service Condition
Do not use the clamp when any damage, defect, or questionable condition is present.

Safety and Load Limits

Treat the Clamp as One Part of the Complete Installation.

Do not exceed the documented 10 kg / 22 lb safe working load.
Do not exceed the allowable load capacity of the supporting truss, tube, pipe, fixture, or attachment hardware.
Use the clamp only on verified tubing measuring between 18 mm and 20 mm outside diameter.
Fully inspect the clamp before each use and remove it from service when damage or defects are present.
Use an independently rated safety cable for maximum security and whenever required by the fixture manufacturer or installation rules.
The purchase of this clamp does not authorize or approve a specific installation or use.
A licensed professional engineer must review structures, lighting plots, and other clamp uses where required.
