EVT50A-S105 105 mm / 4.1 in Female Truss Spacer.
A Female-to-Female Spacer for 50 mm Tubing and Modular 290 mm Conical Truss Builds.
The EVT50A-S105 is a 105 mm / 4.1 in female-to-female aluminum truss spacer for compatible 50 mm / 2 in tubing and 290 mm conical truss systems. Its receiver holes on both ends create a fixed spacing bridge between adjoining compatible female truss ends. The spacer changes connection geometry at one joint; it is not a truss section, independent support point, or direct load-attachment location. Connecting hardware is not included; see the Technical Reference for required connection hardware. Verify fit, full coupler seating, pin engagement, retention, and the complete engineered structure before lifting or applying load.
Product Facts
Product Overview
A 105 mm Female Spacer for One Compatible 50 mm Tube and 290 mm Conical Truss Connection.
The EVT50A-S105 is a female-to-female spacer with receiver holes at both ends. It creates a fixed 105 mm / 4.1 in spacing bridge in a compatible 50 mm tubing and 290 mm conical truss assembly. The female receiver configuration interfaces with compatible conical connection hardware; consult the Technical Reference for the required hardware for one connection.
What It Changes
It Adds 105 mm at One Joint. It Does Not Establish a New Structural Rating.
When installed in a compatible conical connection, the spacer creates a fixed 105 mm / 4.1 in bridge between adjoining truss ends. It does not independently establish allowable span, load capacity, pick-point location, support arrangement, or approval for the modified structure. Evaluate the complete system after the connection geometry has changed.
Selection Guidance
Select the S105 When The Layout Requires a 105 mm Female-to-Female Bridge.
Use the EVT50A-S105 when the documented layout requires a fixed 105 mm / 4.1 in spacing bridge between compatible female truss ends and calls for a female-to-female receiver configuration. Do not use it as an adjustable fitting, a generic extension, a repair for damaged truss, or a substitute for a different measured correction.

System Compatibility
F34, EVT290S, and Compatible 290 mm Conical Truss Systems.
The EVT50A-S105 is designed for compatible 50 mm / 2 in tubing and 290 mm conical-connector truss systems, including F34 and EVT290S. Before mixing brands or separately sourced components, verify actual receiver spacing, conical-coupler dimensions, chord geometry, pin alignment, full seating, and the complete structural plan.
Installation Checks
Confirm the 105 mm Requirement. Then Verify the Complete Connection.
The female spacer creates a bridge within a conical truss connection. Install it only after confirming the required 105 mm correction, inspecting the components, test-fitting the connection, and verifying full seating, pins, retention hardware, and the complete structural plan.
Safety and Engineering
The Spacer Changes Connection Geometry. It Does Not Override System Limits.
The EVT50A-S105 is a structural connection component. It does not independently establish a load rating for the modified structure. Do not exceed the capacity of the spacer or the truss system it modifies. Do not support loads directly from the spacer connection point. Review the complete structure—including the modified connection—for the actual installation.
Product Questions
Frequently Asked Questions.
What does the EVT50A-S105 do?
It creates a fixed 105 mm / 4.1 in female-to-female spacing bridge between compatible truss ends within a compatible conical truss connection.
Is connecting hardware included?
No. The spacer is supplied without connecting hardware. See Technical Reference for the required hardware per connection.
What tubing and truss systems does it fit?
It is designed for compatible 50 mm / 2 in tubing and 290 mm conical truss systems, including F34 and EVT290S. Verify physical fit and the complete connection before use.
What are its documented dimensions?
The product data lists 50 x 105 x 50 mm dimensions, with a fixed 105 mm / 4.1 in spacing or overall length.
Can it be used as a load point?
No. Do not attach or support loads directly from the spacer connection point. The complete structure must be evaluated for the actual installation.
How much does it weigh?
The listed product weight is 0.73 lb / 0.33 kg.
