Tube Compatibility

Designed for 24–27 mm Tubing and Compatible Small Truss Systems.

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

24 mm Minimum
Do not install on tubing smaller than the documented minimum diameter.
27 mm Maximum
Do not force the clamp onto tubing larger than the documented maximum diameter.
25 mm Nominal Systems
Suitable for compatible 25 mm-class tubing and small truss systems within the documented fit range.
Verify Before Use
Confirm actual tube 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 tube measures between 24 mm and 27 mm outside diameter.
02 — Inspect the Clamp
Check the aluminum body, bolt, washers, wingnut, and threads before use.
03 — Seat the Clamp
Position the clamp evenly around the tube without obstruction or misalignment.
04 — Attach the Fixture
Use compatible attachment hardware and follow the fixture manufacturer's instructions.
05 — Tighten Correctly
Secure the wingnut without deforming the tube or damaging the clamp threads.
06 — Add Secondary Safety
Use an independently rated safety cable whenever required.

Inspection and Maintenance

Inspect Before Every Use. Remove Damaged Clamps from Service.

Clamp Body
Check for cracks, deformation, chipped coating, corrosion, or impact damage.
Attachment Bolt
Inspect the M6 bolt and threads for stretching, stripping, or contamination.
Washers and Wingnut
Confirm all hardware is present, undamaged, and correctly seated.
Tube Contact
Keep contact surfaces clean and free from debris that could prevent full seating.
Service Records
Follow inspection and recordkeeping procedures required by the employer, venue, or authority having jurisdiction.

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 tube, truss, fixture, bolt, safety cable, and all connected hardware must also be properly rated.
Use the clamp only on tubing within the documented 24–27 mm outside-diameter range.
Inspect the EVT25C-BLCSS 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.
