In short: The Motion Labs Overmold Y Dual Twist Hoist Cable, also called a "Double Hubbell," carries chain hoist power and control on one 16 AWG, 7-conductor SEOOW cable. At each end, an overmolded Y splits the cable into an L16-20 twistlock power connector and an L14-20 twistlock control connector, wired to pinout P/O 0900-01. This 75 ft version (part number 1410-04-30-02-001) includes a strain relief dog clip for the hoist end and has clear heat shrink on each end for labels.

Why overmolded

Why choose an overmolded Dual Twist hoist cable?

Dual Twist hoist systems use two twistlock connections, one for power and one for control. Instead of running two separate cables to each hoist, the Motion Labs Overmold Y carries both on a single 16/7 cable and splits them only at the ends. Overmolding replaces the metal backshells, which Motion Labs says improves shock absorption, pull strength and strain and flex relief.

One cable, two connections

An overmolded Y at each end splits a single 16/7 cable into separate L16-20 power and L14-20 control connectors.

Overmolded strain relief

A rubberized overmold replaces metal backshells, holding the connectors and cable together as one piece through every load-in.

Two-step molding

An injected polymer first encapsulates the conductors and pins or sockets. A rubberized outer layer is then molded over the assembly.

16/7 SEOOW cable

16 AWG, 7-conductor SEOOW cable with an oil-resistant jacket rated for outdoor use.

Dog clip included

A strain relief dog clip on the hoist end takes the cable's weight off the connectors where they plug into the hoist.

Ready to label

Clear heat shrink on each end gives you a protected spot for cable labels and inventory tags.

On the deck & in the air

Where is a Dual Twist hoist cable used?

Riggers and production crews use Dual Twist cables to connect chain hoists that take power and control through separate twistlock connectors:

Concert and touring rigs with Dual Twist hoists and controllers
Arena and stadium load-ins with many hoists across the grid
Corporate and live events flying truss, video walls and scenery
Theatre and venue rigging with Dual Twist hoist systems
Film and TV stages flying lighting truss or set pieces
Rental house inventory, where overmolded ends hold up longer between repairs

Using it well

How do you use a Dual Twist hoist cable?

Confirm the connectors and pinout. This version uses L16-20 power and L14-20 control, wired to pinout P/O 0900-01. Check that this matches your hoist and controller before you order.
Size the load to the cable. The 20A twistlock connectors aren't the limit. Size the hoist load to the 16/7 cable's rating; check the hoist's nameplate current.
Connect power and control. Plug the L16-20 leg into the power receptacle and the L14-20 leg into the control receptacle at the controller and the hoist. The two configurations are keyed differently, so they can't be swapped.
Clip it at the hoist. Attach the dog clip at the hoist end so the cable's weight hangs on the clip, not the connectors.
Route it safely. Keep the cable clear of the chain, moving loads and truss, and connect with the controller off.

Hoist operation should be carried out by qualified riggers following the hoist and controller manufacturers' instructions and your venue's rigging rules.

Questions

Motion Labs Dual Twist hoist cable frequently asked questions

What is the Motion Labs Overmold Y Dual Twist Hoist Cable?

It is a chain hoist cable that carries power and control on one 16/7 SEOOW cable and splits into separate twistlock connectors at each end with an overmolded Y. This version has L16-20 power and L14-20 control connectors, pinout P/O 0900-01, a dog clip and clear heat shrink on each end. The 75 ft length is part number 1410-04-30-02-001.

What is a Double Hubbell hoist cable?

Double Hubbell is a common name for a Dual Twist hoist cable, which uses two twistlock connectors at each end, one for hoist power and one for control. The name comes from the Hubbell Twist-Lock connectors long used for these connections.

What do the L16-20 and L14-20 connectors carry?

The L16-20 connector carries hoist power. L16-20 is a NEMA locking configuration rated 20A at 480V three-phase. The L14-20 connector carries the control connection. L14-20 is a NEMA locking configuration rated 20A at 125/250V.

What is the difference between the L16-20 and L5-20 versions?

Both versions use an L14-20 control connector. This version uses L16-20 for power with pinout P/O 0900-01. The other version uses L5-20 for power with pinout P/O 1100-01. Match the version to the connectors and pinout on your hoist and controller.

What is the amp rating of the Dual Twist hoist cable?

Motion Labs doesn't list a separate amp rating for this cable. On its 7 pin hoist cables, Motion Labs rates the same 16/7 SEOOW cable at 13A, so size the hoist load to the cable rather than to the 20A twistlock connectors, and check the hoist's nameplate current.

Why is an overmolded hoist cable better than one with metal backshells?

Overmolding replaces the metal backshells and locks the cable and connectors together. Motion Labs says this improves shock absorption, pull strength and strain and flex relief.

What lengths are available?

Motion Labs makes it in 25, 50, 75, 100, 125 and 150 ft lengths, in both the L16-20/L14-20 and L5-20/L14-20 versions.

Does the cable include a dog clip?

Yes. Every length includes a strain relief dog clip. On the 125 ft and 150 ft versions, Motion Labs lists the dog clip on the motor end.
