Common Applications

Adjust Truss-Leg Height for Level Installation.

The EVT290S-Spindel provides controlled height adjustment at a 290 mm square-truss leg. Use it to set the required truss-foot height during setup and to help level the assembled truss system where floor conditions vary. Confirm all support points, base components, loads, bracing, anchorage or ballast, surface conditions, and project-specific requirements as part of the complete approved truss system.

01
Trade Show Booths
Set specified truss-leg heights for exhibit systems where floor conditions or finished-floor requirements must be addressed during setup.
02
Stage and Scenic Systems
Use within approved truss systems that require controlled adjustment at a leg connection before the system is loaded.
03
Production Environments
Set the selected support height for truss systems used around lighting, AV, scenic, display, or production equipment.
04
Uneven Floor Conditions
Use where the approved truss system requires controlled height adjustment to address minor variations in the support surface.

Leveling and Height Adjustment

Adjust the Truss Foot During Setup, Then Verify the Complete Support Arrangement.

The Spindel is adjusted by controlled rotation of its threaded screwjack. Establish the selected height as part of the approved truss-system setup process. Confirm that each support point, truss leg, base component, connection, and bearing surface is appropriate for the actual assembled system before loading or lifting.

Set the Selected Height
Adjust the screwjack to establish the required truss-foot height before the system is subjected to its intended loading condition.
Check Support Contact
Confirm full, stable contact between the support foot and the bearing surface before proceeding with the complete assembly.
Review Every Support Point
Confirm that all support points are set according to the approved truss system, not only the leg using the adjustable Spindel component.
Do Not Treat Adjustment as Anchoring
Height adjustment does not provide anchorage, ballast, bracing, or independent approval for the complete truss system.

Included Connection Hardware

One Hardware Set for One Connecting Side Only.

The EVT290S-Spindel includes one set of conical connection hardware for one connecting side only. Confirm the current product package, approved truss system, and connection schedule before assembly.

One Connecting Side
The included hardware set is intended for the Spindel’s truss connection.
4 Conical Couplers
One hardware set includes four conical couplers for the truss connection.
8 Tapered Pins
Eight tapered pins secure the conical couplers through the aligned receiver positions.
8 R-Clips
Eight R-clips retain the tapered pins after installation. Confirm that every installed tapered pin has its required R-clip before the truss system is lifted, moved, or loaded.

System Compatibility

EVT290S, F34, and 290 mm Square Truss Systems.

The EVT290S-Spindel is designed around a nominal 290 mm square profile and 50 mm main tubing. System fit requires more than matching nominal outside dimensions. Receiver position, conical connector details, chord spacing, component orientation, support arrangement, and applicable structural data must also correspond.

EVT290S System
The Spindel is configured for the EVT290S nominal 290 mm square-truss profile.
F34 System
The product is intended for F34-style 290 mm square-truss systems with matching connection details.
Other 290 mm Systems
Other 290 mm square conical systems should be dimensionally verified before the components are combined.
Support-Component Review
Confirm the Spindel, connected truss leg, bearing surface, base components, and complete support arrangement together as part of the approved truss system.
Physical Fit Does Not Establish Structural Equivalence
A component may physically connect to another 290 mm truss component without the complete assembly having equivalent structural properties. Verify connector dimensions, tubing configuration, material, component orientation, system load data, and engineering requirements before combining components from different systems.

Connection and Adjustment

Connect the Spindel, Set the Height, Then Verify the Complete Support Arrangement.

Assembly should be completed by trained personnel using matching components, the approved truss system, and sufficient hardware for every required connection. Establish the selected screwjack setting before the truss system is subjected to its intended loading condition.

01 — Inspect Components
Check the screwjack, main tubing, bracing, welds, receivers, conical couplers, tapered pins, R-clips, and bearing foot for damage or abnormal wear.
02 — Confirm the Support Arrangement
Confirm the Spindel location, selected height, bearing surface, connected truss leg, and required base or support components against the approved truss system.
03 — Connect Truss
Align adjoining truss receivers and install matching conical connection hardware without forcing mismatched components into position.
04 — Secure Connection Hardware
Fully seat the tapered pins and install all required R-clips at the truss connection interface.
05 — Set the Screwjack
Use controlled rotation to establish the selected height while the truss system is in a condition suitable for adjustment.
06 — Verify Before Loading
Confirm height setting, bearing contact, truss alignment, connection security, and the complete support arrangement before loading or lifting.

Safety and Engineering

Height Adjustment Does Not Independently Establish Support Capacity or Stability.

The EVT290S-Spindel does not independently establish a load, span, support, freestanding-structure, or public-facing structure rating. Suitability depends on the complete approved truss system, including connected components, selected support heights, support arrangement, bearing surfaces, bases, bracing, rigging method, applied loads, ballast or anchorage, venue requirements, environmental conditions, and applicable approvals.

Inspect the screwjack, threads, foot, chords, braces, welds, receivers, connection hardware, and adjoining truss before use.
Remove components from service if cracks, permanent deformation, damaged welds, damaged threads, excessive wear, or other structural defects are identified.
Set the required height before the truss system is subjected to its intended loading condition.
Do not treat the listed adjustment range as a load rating or as authorization to adjust the component while the system is loaded.
Confirm full, stable bearing contact on a support surface at every required support point.
Do not treat the Spindel as a substitute for required base components, bracing, ballast, anchorage, or engineered support provisions.
Verify complete seating of all conical couplers, tapered pins, and R-clips before loading the truss system.
Have the complete truss system reviewed by a licensed professional engineer when required by the configuration, application, or jurisdiction.

Product Questions

EVT290S-Spindel Frequently Asked Questions.

When should I select the EVT290S-Spindel instead of a fixed-height truss support component?

Select the Spindel when the approved truss system requires controlled height adjustment at a truss leg. Select a fixed-height support component when the required support height is known and adjustment is not required.

Can the screwjack be adjusted after the truss system has been loaded?

Do not treat the adjustment feature as authorization to change the selected support height under load. Establish the screwjack setting during controlled assembly before the truss system is lifted, supported, or subjected to its intended loading condition, unless a project-specific engineered procedure establishes otherwise.

Does the Spindel replace a base plate, ballast, anchorage, or bracing?

No. The Spindel is a height-adjustable truss-leg component. It does not replace any base component, ballast, anchorage, bracing, or other support provision required by the complete approved truss system.

Can the Spindel be combined with another 290 mm square-truss system?

Confirm receiver positions, conical connection details, chord spacing, component orientation, matching hardware, support requirements, system load data, and applicable engineering requirements before combining components. A physical connection alone does not establish structural equivalence.
