Residential Garage Door Slide Lock for 2" Track – SSC Part 503

The Residential 2" Slide Lock is a simple, reliable interior mechanical lock designed specifically for sectional garage doors using 2-inch vertical track.

Mounted on the inside of the garage door, the slide lock uses a manually operated locking bar that extends into an opening in the vertical track. When engaged, the bar physically blocks the door from traveling upward, providing a straightforward mechanical locking point without keys, electricity, batteries, or electronic controls.

This lock is a practical replacement for a bent, damaged, rusted, missing, or worn residential slide lock and is also useful when adding an interior manual lock to a compatible garage door.

Features

• Residential garage door manual slide lock

• Designed specifically for 2" garage door track

• 2-1/4" case width

• Mounts on the interior side of the garage door

• Sliding lock bar engages the vertical track

• Helps prevent the garage door from being raised while engaged

• Simple manual operation

• No key, battery, wiring, or electrical connection required

• Compact design for common residential sectional doors

• Ideal for replacement or new mechanical-lock installations

• Useful for manually operated garage doors and compatible storage applications

How the Slide Lock Works

The slide lock mounts to the inside face of the garage door near the vertical track.

To lock the door, the user manually pushes the locking bar outward. The bar passes through an opening in the vertical track and creates a physical obstruction that prevents the garage door and rollers from traveling upward.

To open the garage door, the locking bar is pulled completely back into the lock body before the door is raised.

The system is entirely mechanical, making it a simple way to secure a compatible garage door from inside the garage.

Designed Specifically for 2" Track

SSC specifies this model for:

2" Garage Door Track Only

This is an important distinction because garage door track is available in different sizes and configurations.

Before ordering, verify that your door uses 2-inch vertical track and that the track contains or can accommodate an appropriate opening for the locking bar.

If your application uses 3" track or requires a lock that can accommodate both 2" and 3" track, a universal slide-lock model may be more appropriate.

Case Width

Case Width: 2-1/4"

The compact lock body is designed for residential sectional garage door applications where space is limited near the vertical track.

When replacing an existing lock, compare the available mounting area and existing hole locations before installation.

Common Applications

The Residential 2" Slide Lock is useful for:

• Residential sectional garage doors

• Manually operated garage doors

• Detached garages

• Storage garages

• Workshops

• Replacing a damaged or missing slide lock

• Restoring an older garage door locking system

• Adding an interior mechanical locking point

• Doors where exterior keyed access is not required

Why Use a Manual Slide Lock?

A manual slide lock provides a direct mechanical connection between the garage door and its vertical track.

Advantages include:

• Simple construction

• No electrical components

• No batteries to replace

• No keys to lose

• Easy visual confirmation of whether the lock is engaged

• Direct physical locking of the garage door track

• Low-maintenance operation

For a manually operated garage door, this can provide a straightforward way to secure the door from inside.

Residential Slide Lock vs. Universal Slide Lock

This SSC Part 503 is specifically designed for 2" track only.

SSC also offers universal slide locks designed for both 2" and 3" track.

Choose Part 503 when:

• The door has confirmed 2" track

• A compact residential slide lock is desired

• The existing door already uses this style of lock

Choose a universal model when:

• Track size may vary

• 3" track compatibility is required

• A more universal replacement is preferred

Before Ordering

Confirm the following before purchasing:

• Garage door uses 2" vertical track

• Adequate mounting space is available

• Track has an appropriate opening for the locking bar

• Existing rollers and hinges will not interfere with the lock

• Door configuration allows the locking bar to engage fully

Garage door slide locks are not universally interchangeable, so matching the track size and mounting position is important.

Installation Notes

Position the slide lock on the inside of the garage door so the locking bar lines up correctly with the vertical track.

Before permanently fastening the lock:

• Verify the bar enters the track opening smoothly

• Confirm the bar can fully engage

• Confirm the bar can fully retract

• Make sure it does not contact a roller or hinge

• Check that the garage door travels freely when unlocked

After installation, operate the slide lock several times manually before returning the garage door to regular use.

Important for Automatic Garage Door Openers

If the garage door is connected to an electric garage door opener, the slide lock must be completely disengaged before operating the opener.

Never activate an automatic opener while the slide lock is engaged.

Trying to open a mechanically locked door with an electric opener can damage:

• The garage door opener

• Door sections

• Vertical track

• Slide lock

• Rollers

• Hinges

• Other garage door hardware

For doors used regularly with an automatic opener, take extra care to verify the slide lock position before each operating cycle.

Safety

Always confirm the slide-lock bar is fully retracted before opening the garage door.

Never force a door that remains mechanically locked.

Garage doors are heavy moving systems and may contain springs and cables under substantial tension. Work involving the door's spring or counterbalance system should be performed only by individuals familiar with proper garage door service and safety procedures.
