Truss Compatibility

Designed for 38–41 mm Pipe, Tubing, and Compatible Truss Chords.

Compatibility depends on actual outside diameter, tube condition, clamp seating, attachment hardware, and the load requirements of the complete installation.

38 mm Minimum

Do not install on tubing smaller than the documented minimum diameter.

41 mm Maximum

Do not force the clamp onto tubing larger than the documented maximum diameter.

Pipe, Tube, or Truss

Suitable for compatible members within the documented diameter range.

Verify Before Use

Confirm actual diameter, wall condition, seating, and engineering requirements before loading.

Installation Sequence

Install with Full Tube Contact and Verified Hardware.

01 — Verify Tube Diameter

Confirm the supporting member measures between 38 mm and 41 mm outside diameter.

02 — Inspect the Clamp

Check the aluminum body, M10 bolt, spring lock washer, wingnut, and threads.

03 — Open the Collar

Turn the wingnut counterclockwise to release the bolt and open the clamp.

04 — Position the Clamp

Place the EVT40C-ALB in its final position on the pipe, tube, or truss chord.

05 — Tighten Clockwise

Turn the wingnut clockwise until the clamp is securely seated.

06 — Add Secondary Safety

Use an independently rated safety cable whenever required.

Inspection and Maintenance

Inspect Before Every Use. Remove Damaged Hardware from Service.

Clamp Body

Check for cracks, deformation, deep gouges, corrosion, or impact damage.

M10 Bolt and Threads

Inspect for stretching, stripping, galling, or contamination.

Spring Lock Washer

Confirm the washer is present, undamaged, and correctly seated.

Wingnut and Collar

Verify smooth operation and full closure around the supporting member.

Tube Contact Surfaces

Keep contact areas clean and free from debris that could prevent full seating.

Safety and Load Limits

Treat the Clamp Rating as One Part of the Complete Installation.

Do not exceed the documented 100 kg / 220 lb maximum load.

The supporting pipe, tube, truss, fixture, attachment hardware, safety cable, and all connected components must also be properly rated.

Use the clamp only on members within the documented 38–41 mm outside-diameter range.

Inspect the EVT40C-ALB before use and remove damaged or defective clamps from service.

Use an independently rated safety cable for overhead fixtures whenever required.

Do not modify, drill, grind, weld, or heat the clamp body.

A licensed professional engineer should review structures, lighting plots, and other clamp uses where required.
