EVT290A-CS55 55 mm Male Truss Coupler Spacer.
Adds 55 mm at One Compatible 290 mm Conical Truss Connection.
The EVT290A-CS55 is a double-ended male conical aluminum spacer that adds a fixed 55 mm / 2.16 in at one compatible 290 mm truss connection. Before installation, confirm the connection requires 55 mm and that the complete joint—including truss receivers, conical coupler, coupler-pin length, r-clip fit, and retaining hardware—remains suitable with the spacer installed. It is not a truss section, independent support point, or direct load-attachment location.
Product Facts
What It Is
A Fixed 55 mm Coupler Spacer for One Specific Connection Condition.
The EVT290A-CS55 is a single-piece, double-ended male conical spacer with an integrated 55 mm collar. It is manufactured from Aluminum Alloy EN AW-6061 T6 with a brushed aluminum finish. Its fixed 55 mm geometry must match the approved requirement at the selected compatible connection.
What It Changes
It Adds 55 mm to One Joint. It Does Not Create a New Load Point.
The CS55 adds 55 mm / 2.16 in at the selected compatible connection. It does not independently establish a load rating, allowable span, pick-point location, or support arrangement for the modified truss structure.
What the Spacer Supports
Close a Larger Measured Difference at a Single Connection.
Use the EVT290A-CS55 where a verified compatible truss connection requires a 55 mm adjustment. Confirm the receiver interface, selected coupler, required pins and r-clips, complete layout, support conditions, and applicable engineering requirements before modifying a connection.
Selection Guidance
Select the CS55 When the Truss System Requires a 55 mm Addition.
Use the EVT290A-CS55 only when the connection requires a fixed 55 mm / 2.16 in addition at one compatible joint. Do not use it as an adjustable fitting, generic extension, repair for damaged truss, or substitute for a different measured requirement.
Included Components
One Spacer. Retaining Hardware Sold Separately.
The EVT290A-CS55 ships as one double-ended male conical spacer. It does not include coupler-pins, r-clips, or other retaining hardware. Select and verify all required hardware for the completed approved connection before installation.
Use the selected spacer only for the approved measurement adjustment. Do not stack multiple spacers at one connection point without project-specific engineering approval for the completed connection.

System Compatibility
Use CS55 in Compatible 290 mm Conical Truss Connections.
The EVT290A-CS55 is designed for compatible 290 mm conical truss connection points, including EVT290S and F34-style systems. Confirm receiver spacing, coupler dimensions, chord interfaces, pin length, r-clip fit, complete engagement, and engineering data before combining separately sourced components or lifting the completed structure.
A spacer can physically fit within a connection without the completed modified structure having approved support or load conditions. Verify all interfaces, documentation, hardware, and project-specific engineering before use.
Installation Overview
Confirm the 55 mm Requirement. Then Confirm the Entire Connection.
The spacer changes the effective length and connection depth at one joint. Install it only after confirming the 55 mm addition, inspecting the components, test-fitting the connection, and confirming coupler engagement, pins, r-clips, and the complete structural plan.
Safety and Engineering
The Spacer Changes One Connection. It Does Not Override System Limits.
The EVT290A-CS55 does not independently establish a load rating for the modified structure. Evaluate the completed layout for support conditions, joint engagement, installed loads, handling method, and engineering requirements. Do not support loads directly from the spacer connection unless the exact approved load case specifically permits it.
Variant Relationship
Start With the Gap You Measured. Then Choose the Matching Spacer.
Spacer length and finish must match the approved connection requirement. Do not stack, substitute, or combine variants unless the exact arrangement is approved for the complete structure.
A 55 mm requirement calls for this single-piece spacer, not a combination of smaller units. Do not stack spacers or combine dimensions without engineering approval for the completed connection.
Product Questions
EVT290A-CS55 Questions.
What does the CS55 do?
It adds a fixed 55 mm / 2.16 in at one compatible 290 mm conical truss connection.
Are coupler-pins included?
No. The product includes the 55 mm spacer only. Coupler-pins and r-clips must be selected separately for the completed verified connection.
Can it be used as a load point?
Do not attach or support loads directly from the spacer connection unless the exact approved load case specifically permits it.
Can this spacer be combined with other spacers?
Do not stack or combine spacers unless the exact configuration has project-specific engineering approval for the completed structure.
