When someone says they can’t wear a lock, remember that NOT ALL LOCKS ARE CREATED EQUAL.The New Suction Lock combines a lock system with an air sealing valve to create an airtight suction* socket. This feature: - Reduces pistoning
- Reduces traction or milking on the limb
- Improves proprioception
- Reduces tension and pressure on the limb
- Improves suspension
Specific improvements made to create the Suction Lock: - O-ring on housing seals easily
- New funnel shape helps feed the pin into the lock
- Higher engagement point makes getting initial engagement easier
- Stronger, more stable engagement of pin
- Simpler, faster, and easier fabrication

The airtight friction, or “suction” that is created helps to reduce movement and milking of the limb inside the socket, thus reducing risk of skin irritation and breakdown. Even if only a small amount of movement is reduced, if that is multiplied by a thousands steps, that makes a big difference. *Because the pin works independently of the valve, the pin could be removed to document the suction function of your socket. In most cases the Suction Lock bills as L5671. But in some situations involving comfort, donning, blood flow, or skin issues it may be medically justified to bill L5647.

ORDER/PARTS(back to top) | The anchor of the suction lock drops right into the casting handle before the mold is filled. This builds the anchor right into the mold, taking the guess work out of lock location. The anchor also has a o-ring to keep resin from entering the lock. Each lock comes with the anchor and other necessary parts for fabrication. | Regardless of what liner you use, we have a molded distal cushion to help create an intimate fit between the lock and the liner. It also helps prevent the pin from being in between clicks, and adds some extra cushion
| The NEW Casting Pin and Handle are used in conjunction with new molded distal cushions to create the lock shape and an intimate fit right into the cast. From here the
fabrication anchor can be placed in the handle and the cast is filled. This makes fabrication much faster and easier, without losing your pin location. | | | |

CD112SS small silicone style liner
CD112MS medium silicone style liner
CD112LS large silicone style liner |  | Casting Handle and Pin CD316 (reusable) |  | Casting Handle and Cushion Kit
Includes 1 casting handle, 1 casting pin, and 1 of each size of the distal cushions CD317 |  | CD103WH: Lock Wrench for Suction Lock, Air-Lock and CQLTM Valve
Removes valve body of Air-Lock and CQLTM Valve to access the inside of the lock and the filter of the valve. Wrench is equivalent to 13mm deep well socket. |  | CD103RBC: Release Button Cover
Added to end of release button to make it easier for patients to release the lock. Ideal for geriatric or other lower dexterity or limited hand strength patients. |  | CD103FF: Fast Four Connector
Connector is used with the Suction Lock, Air-Lock and IntegratorTM. Connector will key directly onto the bottom of the lock or IntegratorTM and is thermoformed or laminated into socket. Used in test sockets and definitive sockets when align- ment is not an issue.
Pediatric versions available. |  | CD103AF: Alignable Four Connector
Connector is used with Suction Lock, Air-Lock and IntegratorTM. Can be offset from the bottom of the lock and fabricated into the laminated socket. Used in definitive sockets when customer is needing to offset the alignment. Pediatric versions available. | | CD106: Alignment Coupler
Alignment Coupler is used for dynamic alignment during test socket fitting. Connects to standard four hole and can offset the prosthetic alignment (foot) from the bottom of the socket. Up to 265 lbs.
Not for use in definitive sockets. Offset for ML and AP of .64in.
| | CD103ELD: Exo Lamination Plug
Used when fabricating Suction Lock and Air-Lock in exo sockets. The extra length of this plug versus the standard makes it easier to access the release button and valve body.

TECHNICAL/FITTING TIPS(back to top) The Suction Lock was designed to have prosthetic alignment built into the socket, independent of pin alignment in one lamination. The Aligned Connector is used in this scenario to facilitate the single stage lamination, reducing time and materials.  |  | | The Four Connector can be laminated or thermoformed. It slides onto the bottom of the lock in the center hole, or with a .33 inches of offset using the 2nd position. | The Aligned Connector has nearly infinite offset capability. In M/L, AP, and in angle. This connector eliminates the need for any offset componentry underneath the lock.
|  |  | | The Alignment Coupler is used during test fitting for dynamic alignment. Typically co-poly is used to allow for longer period test fitting, easy and fast fabrication, and for its ability to seal against itself keeping the socket airtight. | |
