The BeBecome sliding door security bar is built from a 1″ diameter painted metal bar, offering higher durability than standard 3/5″ bars.

Quick assembly enables placement within minutes, and the rugged construction aims to withstand daily use in apartment or home setups. The bar includes rubber tips to protect floors and reduce movement while blocking the door from being forced open.
Exit Security SB-01-0036 Security Bar (36″)
Designed specifically for outswing doors, the SB-01-0036 includes a wall mounting bracket for storage when the door is unlocked. The 36″ bar provides a solid, visible deterrent and an easy add-on to enhance back-door security. Its storage bracket helps keep unused barriers organized, reducing clutter near entryways and ensuring the bar is ready when needed.
SECURITYMAN Sliding Door Security Bar
SECURITYMAN offers the widest adjustment range among similar products, from 18.75″ to 51.1″. The design supports multiple configurations (two bars or three bars) to tailor fit per door width. It is installed by drilling into the door frame, creating a secure, rigid barrier that resists body pressure and acts as a practical deterrent against intruders. The product emphasizes quick installation and a dependable, long-lasting service life.
AceMining Sliding Door Security Bar (White)
The AceMining model uses a heavy-duty 1″ bar with an adjustable length from 20.5″ to 50″. It is described as capable of withstanding substantial force and includes an extension bar for versatile sizing. The product notes emphasize its dual-use capability as both door and window security, with alloy connections designed to extend the life of the bar. Weighing less than two and a half pounds, it is suitable for travel or apartment living where portability matters.
Rerishom Door Security Bar (2 Pack)
Rerishom offers a 2-pack option with an adjustable length range of 17.5″ to 46″ (and 43″ for sliding doors). The bars feature a robust 1.57″ diameter, delivering high resistance to forcible entry and a comprehensive material upgrade for enhanced durability. The dual-pack option provides value for households seeking multiple door protections or replacements for different entryways, with a focus on reliable, long-term security.
BeBecome Sliding Door Security Bar (Black)
This variation mirrors the BeBecome design with a 50″ total length and an adjustable 17.7″–50.5″ range. The black finish provides a different aesthetic while maintaining the same durable 1″ steel construction and rubber-tipped feet for floor protection. Suitable for homes and apartments seeking a sturdy back-door barrier with straightforward setup.
Exit Security SB-010048 Single Outswing Door Bar
Designed for 48″ door widths and outswing doors, this single-bar bar prioritizes a simple, focused approach to back-door security. The product guidance highlights door width compatibility and a straightforward deployment. It serves well in setups where a lightweight, compact barrier is preferred and where exterior doors open outward, requiring a barrier that aligns with non-traditional frame configurations.
Buying Guide: Key Purchase Considerations
- Door type and width: Confirm whether your door swings in or out and measure width to select a bar with an appropriate length range and mounting method.
- Material and durability: Look for 1″ diameter steel or reinforced alloys for higher resistance to force. Rubber tips help protect floors and improve grip.
- Mounting method: Some bars require drilling or brackets; others are simple telescoping units. Consider whether you want a hidden, stowable, or visibly strong barrier.
- Adjustability: A wider adjustment range increases compatibility across multiple doors or rental spaces. Multi-bar configurations enhance fit precision.
- Portability and storage: If you travel or move often, choose lighter units or those with carry-friendly designs. Brackets that store securely can reduce clutter.
- Safety and usage notes: Ensure the bar sits flush in the track or frame to prevent impulsive lifting. Follow installation guidelines to avoid gaps that could compromise security.
- Maintenance: Check rubber feet, coatings, and joints for wear. Replace components showing signs of degradation to maintain effectiveness.
- Value vs. coverage: Two-pack or multi-pack options offer cost-efficient coverage for multiple entry points, especially for apartments with several doors.
These products provide a range of options from simple protection to highly adjustable, heavy-duty solutions. When selecting a back door security bar, balance door compatibility, installation effort, and the level of deterrence you need to meet your security goals.
