### What Is a Garage Door Bottom Bracket?

The bottom bracket mounts to the lowest section of the garage door.

It serves two important functions:

- Supports the bottom roller assembly
- Provides the connection point for the garage door lift cable

The lift cable runs from the bottom bracket upward to the cable drum or extension spring system.

Because the lift cable is connected to the bottom fixture, the bracket carries a significant portion of the door's lifting force during operation.

### Removable Roller Carrier

The SRBB-50 includes a removable roller carrier.

This design allows the roller portion of the assembly to be serviced or replaced without necessarily replacing the entire bottom bracket.

The removable carrier can also provide additional installation and adjustment flexibility compared with fixed-carrier bottom brackets.

### Sold as a Pair

This listing includes:

- 1 Left-Side Bottom Bracket
- 1 Right-Side Bottom Bracket

One pair is normally required for one sectional garage door.

Replacing bottom brackets as a matched pair is recommended when both original fixtures show similar age, wear, corrosion, or damage.

### Common Replacement Reasons

Replace the bottom brackets if the existing parts are:

- Bent
- Cracked
- Severely rusted
- Worn around the roller carrier
- Damaged at the cable attachment point
- Distorted after a cable or spring failure
- Missing or improperly modified

A damaged bottom bracket can affect cable alignment, roller travel, and overall garage door operation.

### Compatibility

The SRBB-50 is intended for compatible residential sectional garage doors.

Before ordering, compare:

- Existing bracket dimensions
- Door thickness
- Roller carrier position
- Cable attachment configuration
- Existing bolt pattern
- Track and roller size
- Original fixture style

Do not select a bottom bracket based only on general appearance.

### SRBB-50 vs. Other Residential Bottom Brackets

SSC offers several residential bottom bracket styles.

The SRBB-50 is distinguished by its:

- 13-gauge construction
- 5-1/4" height
- 2-3/4" width
- 1.30" side flange
- Removable roller carrier

Other models such as BB-100 or RBB-75 use different dimensions and configurations.

Always verify the original hardware before ordering.

### Package Contents

Includes:

- 2 – SSC SRBB-50 Residential Bottom Brackets
- Removable Roller Carrier Assemblies

Rollers, lift cables, fasteners, bottom fixtures, springs, and other garage door hardware are not included unless specifically stated otherwise.

### IMPORTANT SAFETY WARNING

Garage door bottom brackets are connected directly to the lift cables and can be under extreme spring tension.

DO NOT loosen, remove, or adjust a bottom bracket while the garage door counterbalance system is under tension.

Improper removal can cause the lift cable, bracket, spring system, or garage door to move violently and may result in serious injury or property damage.

Bottom bracket replacement should be performed by a trained garage door technician familiar with torsion and extension spring systems.

Before servicing:

- Secure the garage door
- Properly release spring tension
- Verify lift cables are unloaded
- Follow applicable manufacturer procedures
- Replace damaged cables or related hardware as necessary

After installation, verify that both lift cables are properly seated, the rollers travel smoothly, and the garage door remains level and balanced through its full travel.
