EVT290A-CS20 20 mm Male Truss Coupler Spacer.
Adds 20 mm at One Compatible 290 mm Conical Truss Connection.
The EVT290A-CS20 is a double-ended male conical aluminum spacer that adds a fixed 20 mm / 0.79 in at one compatible 290 mm truss connection. Before installation, confirm the connection requires 20 mm and the complete joint—including receiver spacing, coupler engagement, coupler-pin length, r-clip fit, and all 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 20 mm Spacer for One Specific Connection Condition.
The EVT290A-CS20 is a single-piece, double-ended male conical spacer with an integrated 20 mm collar. It is manufactured from Aluminum Alloy EN AW-6061 T6 with a brushed aluminum finish. Its fixed 20 mm geometry must match the approved requirement at the selected compatible connection.
What It Changes
It Adds 20 mm to One Joint. The Entire Joint Must Still Work as a Joint.
The CS20 adds 20 mm / 0.79 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-CS20 where a verified compatible truss connection requires a 20 mm adjustment. Confirm the receiver interface, selected coupler, required pins and r-clips, complete layout, support conditions, and applicable engineering requirements before modifying any truss connection.
Selection Guidance
Select It Only for an Actual 20 mm Need. Do Not Treat It as Two 10 mm Decisions.
A 20 mm spacer modifies one connection as one component. Select it only where the approved system requires 20 mm / 0.79 in at that joint and the coupler, coupler-pins, r-clips, and truss receivers are confirmed to work together as a complete connection.
Included Components
One Spacer. Retaining Hardware Sold Separately.
The EVT290A-CS20 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 complete 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 CS20 in Compatible 290 mm Conical Truss Connections.
The EVT290A-CS20 is a double-ended male conical spacer for compatible 290 mm conical truss connections. Compatibility requires matching receiver spacing, conical coupler dimensions, chord interfaces, coupler-pin length, r-clip fit, complete engagement, and engineering data for the modified 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 20 mm Joint Before It Enters Service.
Install CS20 only in a verified compatible connection using serviceable components, correct pins and r-clips, current manufacturer instructions, and the approved project plan. Do not force a spacer or connection into alignment.
Safety and Engineering
A 20 mm Change Requires Complete Joint Confirmation.
The EVT290A-CS20 does not independently establish a load rating for the modified structure. The spacer changes connection geometry, so 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
The Dimension Comes First. The Finish Comes Second.
Choose the single spacer whose fixed length matches the approved connection requirement. A black-finish version should be selected only when the same dimensional requirement also needs a black finish.
A 20 mm requirement calls for this single-piece spacer, not two stacked 10 mm units. Do not stack spacers or combine dimensions without engineering approval for the completed connection.
Product Questions
EVT290A-CS20 Questions.
What does the CS20 do?
It adds 20 mm / 0.79 in at one compatible 290 mm conical truss connection.
Why must engagement be checked?
The 20 mm collar changes connection depth, so the complete joint must retain suitable coupler, receiver, coupler-pin, and r-clip engagement.
Are coupler-pins included?
No. The spacer is supplied without coupler-pins or r-clips. Select them separately for the completed verified connection.
Can two CS10 spacers replace one CS20?
No. A 20 mm requirement calls for this single-piece spacer. Do not stack spacers or combine dimensions without engineering approval for the completed connection.
