What It Is

A Wrap-Around Clamp for Compatible 48–51 mm Tube and Truss.

The EVT50C-BQR is a medium-duty, lever-lock clamp with a matte black powder-coat finish. It wraps around compatible tubing and is intended for mounting small lights and light-duty accessories when the supported item, attachment hardware, support tube, load direction, and installation method are within the approved configuration.

48–51 mm Outside-Diameter Fit

Designed for tube and truss with an outside diameter from 48 mm to 51 mm, including standard 50 mm truss main chords and 1.900 in / 48.3 mm Schedule 40 pipe.

Wrap-Around Lever Lock

The clamp collar opens around the tube and is secured with a quick-release handle; no tool is required for the clamp mechanism itself.

Matte Black Finish

The matte black powder coat supports visually discreet fixture mounting in black-truss, theatrical, studio, and architectural environments.

Not a Universal Rigging Solution

This product does not establish the capacity of the support structure, fixture, attachment point, or complete overhead system.

When to Select It

Choose It When the Tube Fits, The Load Case Is Approved, and Fast Repositioning Matters.

Select the EVT50C-BQR for compatible 48–51 mm tubing where a lever-operated clamp is appropriate for the planned fixture or accessory. The product source describes it for small lights and light-duty accessories. Do not select it from diameter alone: confirm the actual fixture, attachment method, load direction, support tube, location, and governing safety requirements.

Small Lighting Fixtures

For compatible small lights when fixture mounting, clamp capacity, support structure, and secondary retention are approved for the actual installation.

Light-Duty Accessories

For accessories within the documented capacity and within the approved complete-system configuration.

Black-Truss Environments

For visible black truss or tube where a matte black clamp helps maintain finish continuity.

Fast Fixture Changeovers

For layouts that benefit from tool-free opening and closing of the clamp collar, while preserving the required inspection and locking process.

Tube Compatibility

Fits 48–51 mm Tube, Including Compatible 50 mm Truss Main Chords and 2-Inch Pipe.

Tube outside diameter is the first compatibility check. The source identifies a 48–51 mm range, which includes standard 50 mm truss main chords and 1.900 in / 48.3 mm Schedule 40 pipe. The clamp is not appropriate for smaller 35 mm tube systems, including EVT220-style decorative truss. Confirm the actual outside diameter with a measurement or reliable component documentation before installation.

Compatible Diameter Range

48–51 mm outside diameter, approximately 1.89–2.0 in.

50 mm Truss Chords

Compatible with standard 50 mm main chords when the actual chord diameter and complete installation are verified.

Schedule 40 Pipe

The source identifies 1.900 in / 48.3 mm outside-diameter Schedule 40 pipe as compatible.

Excluded Smaller Tube

Do not use on smaller 35 mm / 1.37 in decorative truss tube or other tubing outside the stated 48–51 mm range.

Included Hardware

Clamp, Attachment Bolt, and Basic Fixture-Mounting Hardware.

The source identifies the quick-release clamp, an M10 × 30 mm bolt, wing nut, and spring lock washer as included. The included hardware does not replace fixture-specific hardware, safety cables, approved secondary retention, or installation-specific engineering requirements.

Installation Checks

Measure the Tube. Close the Lever. Inspect the Complete Attachment.

The source describes a tool-free clamp mechanism: open the collar with the quick-release handle, seat the clamp on compatible tube, close the collar, and lock the handle. The fixture attachment may require a wrench for the M10 hardware. The following is an installation check sequence, not a substitute for manufacturer instructions, local requirements, or a qualified person’s review.

01 — Confirm Tube Diameter

Measure or verify the actual tube outside diameter. It must fall within the documented 48–51 mm range.

02 — Inspect the Clamp

Before use, inspect the clamp body, lever, bolt, wing nut, washer, and attachment point. Remove damaged, bent, cracked, or loose components from service.

03 — Confirm Handle Clearance

Ensure the quick-release handle has sufficient clearance to open, close, and lock without interference from truss braces, fixtures, cable, or scenery.

04 — Seat and Lock the Clamp

Open the collar, position it fully around the compatible tube, close the collar, and lock the handle according to the approved procedure.

05 — Attach the Fixture

Use the included M10 hardware only where it is compatible with the fixture and approved attachment method. Verify the fixture manufacturer’s mounting requirements.

06 — Inspect Before Service

Verify clamp closure, fixture attachment, support condition, load path, and any required secondary retention before the installation enters service.

Safety Limits and Review

The 220 lb Rating Is a Product Fact. The Complete Installation Still Determines Safe Use.

The documented load capacity is 220 lb / 100 kg. Do not interpret that number as a blanket allowance for every orientation, fixture, support tube, dynamic condition, or overhead installation. Safe use depends on the lowest-rated component and the actual system configuration. Verify load direction, attachment method, supporting structure, fixture requirements, applicable codes, and secondary retention for the installation.

Do not exceed the documented 220 lb / 100 kg capacity or the limit of any other component in the complete system, whichever is lower.

Do not use the clamp on tubing smaller than 48 mm or larger than 51 mm outside diameter.

Inspect the lever-lock mechanism before every use; remove the clamp from service if any component is damaged, bent, cracked, or does not lock correctly.

For overhead applications, use independently attached secondary safety retention where required by the approved plan and applicable rules.

Verify the fixture’s mounting point, mounting hardware, and required orientation before using the included M10 bolt assembly.

Do not use the clamp if the quick-release handle cannot be fully operated and locked because of insufficient clearance.

Do not treat the matte black finish as evidence of compatibility, capacity, or suitability.

Have overhead and safety-critical installations reviewed by qualified personnel under the requirements applicable to the site and load case.
