EVT290A-CPCP Coupler-Pin & R-Clip Set.
10-Pack Tapered Steel Hardware for 290 mm Truss.
The EVT290A-CPCP is the essential locking hardware set for standard 290 mm conical truss connections. Each 10-pack includes 10 tapered coupler-pins and 10 r-clips (cotter pins) — the fasteners that secure a conical coupler inside the truss receiver to create a tight, rattle-free joint. The tapered coupler-pin design self-aligns with the coupler and draws the truss sections together when driven in with a steel hammer.
Product Facts
Product Overview
The Locking Hardware Behind Every Conical Truss Joint.
The EVT290A-CPCP supplies the coupler-pins and r-clips that lock a conical coupler inside the truss receiver. The tapered pin design self-aligns with the coupler as it is driven in with a steel hammer, eliminating gaps and drawing the connection tight. Each r-clip then locks its coupler-pin in place, preventing accidental removal.
Common Applications
Restock the Most Commonly Lost Truss Hardware.
Coupler-pins are among the most frequently lost or damaged components in a working truss inventory. The EVT290A-CPCP keeps toolboxes and road cases stocked with the exact replacement hardware needed at every conical connection point. Confirm connection hardware and component condition as part of the approved truss system.
Included Hardware
10 Sets of Locking Hardware in Every Pack.
The EVT290A-CPCP includes 10 tapered coupler-pins and 10 r-clips — enough locking hardware for 10 individual connection points. A steel hammer is required for installation but is not included. Confirm the current product package and connection requirements before use.

System Compatibility
EVT290I, EVT290T, EVT290S, and F34 Truss Systems.
The EVT290A-CPCP is designed for compatible EVT290I I-Beam, EVT290T Triangular, EVT290S Square, and F34-format 290 mm truss systems. Verify pin diameter and taper angle before using with other truss brands, and confirm the pin hole alignment matches the truss receiver before installation.
Connection and Assembly
Seat, Pin, and Verify Every Connection Before Use.
Assembly should be completed by trained personnel using matching components and the approved truss system. The coupler-pin is the primary fastener holding the connection together — never use a mushroomed, bent, or cracked pin.
Safety and Engineering
The Coupler-Pin Is the Primary Fastener.
The coupler-pin is the primary fastener holding a truss connection together, so its condition and installation directly affect the safety of the structure. Inspect every pin and clip before use.
Product Questions
EVT290A-CPCP Frequently Asked Questions.
What is included in the EVT290A-CPCP pack?
Each pack includes 10 tapered coupler-pins and 10 r-clips (cotter pins) — enough locking hardware for 10 individual conical connection points.
What tool is needed to install the coupler-pins?
A steel hammer is used to drive each coupler-pin fully into place. It is not included with the hardware set.
Which truss systems is it compatible with?
It is compatible with EVT290I I-Beam, EVT290T Triangular, and EVT290S Square aluminum truss, as well as F34-format 290 mm truss systems.
How do I know when to replace a coupler-pin?
Inspect for necking, shearing, mushrooming, bends, or cracks before every use. Never use a coupler-pin showing any of these signs.
