Tri-Plates for multi-leg lifting, rigging, towing & mooring.
Durham Lifting supplies Multisec Tri-Plates, also known as Delta Plates, Triangle Plates and Monkey Plates, for compact multi-leg rigging arrangements where controlled load transfer and sling management are important.
Compact connection plates for complex lifting arrangements.
Tri-Plates provide a central connection point within multi-leg lifting arrangements, helping reduce sling congestion and support more balanced load transfer across slings, shackles and load points.
Multi-leg lifting
Bring multiple sling legs together through a compact connection point while helping manage load sharing and the rigging interface.
Offshore, marine & heavy lift
Suitable for demanding rigging, towing and mooring applications, as well as specialist heavy lift and project cargo arrangements.
Standard & bespoke
Standard Tri-Plates are supported by bespoke designs engineered around project-specific WLL, sling, shackle and connection requirements.

Tri-Plate questions.
Are Tri-Plates, Delta Plates and Triangle Plates the same thing?
These terms are commonly used interchangeably for triangular rigging connection plates. The term Monkey Plate is also used in some sectors.
What Working Load Limits are available?
The current Multisec range is published from 2 tonnes up to 700 tonnes WLL, with bespoke designs available for project-specific requirements.
Are Multisec Tri-Plates proof load tested?
Yes. The current Multisec product information states that every Tri-Plate is proof load tested prior to supply and provided with the relevant certification and supporting documentation.
Can a bespoke connection plate be engineered?
Yes. Bespoke configurations can be developed around specific Working Load Limits, sling arrangements, connection layouts, shackle sizes and project requirements.
Need a Tri-Plate or bespoke rigging connection plate?
Send the required WLL, rigging arrangement, connection points and any available drawings. Durham Lifting can route the enquiry to the Multisec engineering team and help define the right solution.
