CLGR® Triangle Plate Delta Plate Triangle Towing Plates, also known as Three Hole Triangle Plate, monkey or delta plates.
It is a triangular flat steel plate with three holes used as an equal-force junction. It joins mooring lines, towing pennants, or chain bridles on vessels and aquaculture installations, distributing load evenly across multiple connection points.
Typically produced from high-tensile mild steel or alloy steel, it is finished with hot-dip galvanizing or epoxy paint for corrosion resistance. Each plate's edges are rounded to prevent rope chafe and extend line life.
The three-hole design equalizes load when using multiple slings and prevents interference between chains, ropes, or shackles during operation. When a minimum gap is required between the plate and the connection point, washers are recommended. Spacers are also available on request.
Suitable for towing, mooring, and aquaculture applications. Available in various sizes. Custom configurations available upon request. Contact us for more details.
