Genie 25605R Inner Slide – Chain Drive T-Rail

This genuine Genie chain-drive inner slide is designed for compatible Genie steel T-rail chain-drive garage door openers.

The inner slide mounts to the opener chain and engages with the outer carriage/trolley assembly, allowing the chain-drive system to transfer movement from the opener to the garage door.

Specifications

Designed for Genie T-Rail Chain Drive Openers

SSC identifies this inner slide as compatible with all Genie T-rail chain-drive operators.

It is used inside the carriage assembly and connects directly to the opener chain.

This style of inner slide is also found on many compatible older Overhead Door steel T-rail chain-drive systems.

How the Inner Slide Works

The opener chain attaches to the inner slide.

During normal operation, the inner slide travels with the chain and engages the outer carriage assembly to:

• Pull the garage door open

• Push the garage door closed

• Transfer chain movement to the door arm

• Re-engage the carriage after use of the emergency release

The inner slide is one of the primary mechanical connections between the opener's drive chain and carriage assembly.

Mounting Hardware Included

The replacement inner slide includes the mounting screws used to attach the slide to the opener chain. Current replacement-parts listings describe the kit as including the inner slide and mounting screws.

Compatible Opener Families

This inner slide is used on numerous Genie T-rail chain-drive models, including select units from families such as:

• Genie PMX Series

• Genie IC Series

• Genie ALC Series

• Genie RCD Series

• Genie CM Series

• Genie LD Series

• Genie SP Series

It is also compatible with various older Overhead Door Legacy and Passport T-rail chain-drive openers using the same carriage architecture.

Always verify the existing rail and carriage design before ordering.

Common Reasons for Replacement

Inspect the inner slide if your opener:

• Runs but does not move the garage door

• Has a carriage that will not properly engage

• Has excessive play inside the trolley assembly

• Has a cracked or damaged inner slide

• Has a chain that moves while the outer carriage remains stationary

• Does not reconnect correctly after the emergency release is used

Similar symptoms can also be caused by a damaged outer carriage, chain, sprocket, or rail.

Works With the Outer Carriage

The inner slide operates inside the compatible Genie T-rail carriage assembly.

If the outer carriage is also cracked, worn, or damaged, inspect both components before completing the repair.

Replacing only the inner slide will not correct damage to the outer carriage or rail.
