Introduction to the RGL DBGLS150 and its key features
RGL DBGLS150 — Electric fail‑safe drop/solenoid bolt for frameless glass doors.Designed specifically for commercial glazing and frameless glass entrances, the DBGLS150 offers a slim aluminium body, high holding force and features tailored to access control installations. Operating at 12 V DC with a rated holding force of 1000 kg, this unit combines a discreet aesthetic with the robustness required for retail, office and public environments. Key features include fail‑safe operation (bolt retracts on power loss), a configurable auto‑relock timer (0 / 3 / 6 / 9 seconds), monitoring contacts for door position and a long‑life motor/solenoid rated for more than 500,000 cycles.
Detailed specifications and benefits
Understanding what makes the DBGLS150 practical for frameless glass doors begins with the technical specifications. Below is a concise breakdown of the product’s main specifications and the benefits these deliver in real installations.
- Manufacturer / Model:RGL DBGLS150 — a purpose‑built glass door drop bolt.
- Material & form factor:Robust aluminium body with a slim profile (Bolt unit: 148 x 42 x 39 mm; Strike/recess: 148 x 42 x 25 mm). The low profile suits narrow glass headers and minimalist aesthetics while remaining durable in everyday use.
- Holding force:1000 kg. This high rating makes the DBGLS150 suitable for commercial access points where physical security and resistance to forced entry are priorities.
- Operating voltage and currents:12 V DC operation; standby current ≈ 120 mA and activation current ≈ 900 mA. Separate standby and activation currents improve energy efficiency by reducing continuous power draw when the bolt is idle.
- Fail‑safe operation:The DBGLS150 is fail‑safe — the bolt retracts when power is removed. This behaviour supports safe egress during a power failure but requires review against local fire and egress regulations.
- Auto‑relock timer:Configurable to 0, 3, 6 or 9 seconds. This lets integrators tune the door behaviour for momentary release or automatic re‑locking after a short delay.
- Bolt dimensions and motion:Bolt diameter ≈ 16 mm and bolt throw ≈ 16 mm — sufficient for secure engagement with a matching strike or recess.
- Glass compatibility:Clamp fixing designed for frameless glass up to 14–15 mm thickness. This eliminates the need for heavy framing or intrusive door modification in many glass door installations.
- Monitoring contacts:SPDT COM/NO/NC monitoring contacts (~250 mA @ 30 V DC — verify on site) for door position/status monitoring and integration with access control panels or alarm systems.
- Durability:Motor/solenoid rated for >500,000 operations, indicating a long service life appropriate for medium‑ to high‑traffic entrances.
- Operating temperature:-10°C to +45°C — suitable for most indoor commercial environments.
Benefits in practice: the DBGLS150 balances discreet design and high mechanical security. Its clamp fixing avoids the need for door frame modifications, the monitoring contacts allow integration into modern access control systems, and the configurable relock timer gives installers flexibility to meet user flow and safety requirements.
Use cases and scenarios where the DBGLS150 excels
The DBGLS150 is designed for frameless glass doors and thrives in contexts that demand both aesthetics and security. Typical use cases include:
- Retail entrances:High‑visibility shopfronts and boutiques where a frameless glass aesthetic is important. The slim aluminium body keeps the look minimal while providing a 1000 kg holding force to delay forced entry attempts.
- Corporate offices:Reception doors, boardroom entries and internal secured access points often use glass doors for transparency and design continuity. The DBGLS150 supports access control integration and monitoring without bulky hardware.
- Hospitality and leisure:Hotel conference rooms, upscale restaurants or spa entrances that use frameless glass benefit from the device’s discreet presence and reliable holding force.
- Public and commercial buildings:Retail malls, bank vestibules and professional suites where heavy foot traffic and security concerns coexist. The high cycle life and robust holding force suit frequent use.
- Retrofits and minimalist interiors:Projects where maintaining the glass door appearance is critical — clamp mounting for 14–15 mm glass avoids extensive door modification.
Installation considerations: because the DBGLS150 is fail‑safe, installations in areas subject to strict fire or egress requirements may need battery backup, fail‑secure alternatives, or additional egress hardware. Qualified installers should verify door swing, glass thickness and required brackets or shims before ordering.
Comparisons with similar products on the market
When choosing a locking solution for glass doors, common alternatives include electromagnetic (mag) locks, rim or tubular devices, and fail‑secure electric bolts. Comparing the DBGLS150 helps clarify where it fits best:
- DBGLS150 vs electromagnetic locks (mag locks):Mag locks typically offer high holding force and simple surface mounting but require a clean header or frame and often look more industrial. The DBGLS150’s mechanical bolt provides positive locking into a strike (mechanical engagement) and is better suited for narrow or frameless glass headers. Mag locks remain popular for heavy duty external doors, but the DBGLS150 is preferable where a discrete, mechanical engagement and compatibility with frameless glass is required.
- DBGLS150 vs fail‑secure electric bolts:Fail‑secure bolts remain locked without power and unlock when power is applied — the opposite of fail‑safe. Fail‑secure is often required where security must be maintained during power loss. The DBGLS150 is fail‑safe, prioritising safe egress during power outages; choose fail‑secure alternatives where building regulations or security policy demand power‑loss locking.
- DBGLS150 vs rim/tubular exit devices for glass doors:Rim and tubular devices integrate with mechanical latches and panic hardware; they are often required by code for single‑leaf egress doors. The DBGLS150 is complementary rather than a replacement for panic hardware — it secures the door when in locked mode but must be coordinated with local egress requirements and panic hardware solutions.
- Power consumption and efficiency:Compared with some solenoid bolts that draw high continuous current, the DBGLS150’s separate standby (≈120 mA) and activation (≈900 mA) currents are energy‑conscious, reducing thermal stress and operational cost over time.
Customer feedback and reviews (illustrative)
Below are anonymised, representative comments based on typical installer and end‑user feedback for this type of product. These are illustrative of the kinds of responses integrators and customers commonly report.
- Installer comment:“Compact and easy to integrate with frameless glass doors. The clamp fit works well for 12–15 mm glass and reduced the need for secondary brackets in most installs.”
- Facility manager:“High holding force gives us confidence at the main entrance — the bolt feels robust and the monitoring contacts make integration with our access control system straightforward.”
- Retail owner:“We appreciated the discrete look and configurable auto‑relock. It locked reliably after short entry delays and didn’t detract from our storefront design.”
- Note on caveats:A few comments commonly surface: ensure compatibility with local fire codes due to fail‑safe behaviour, and verify the strike alignment precisely for smooth operation — both are standard concerns rather than product faults.
Conclusion — why the RGL DBGLS150 is a strong choice
The RGL DBGLS150 electric fail‑safe drop bolt is an excellent option for projects that require a discreet, high‑performance locking solution for frameless glass doors. It balances cosmetic subtlety with mechanical strength (1000 kg holding force), energy‑aware operation, and flexible integration via monitoring contacts and an adjustable auto‑relock timer. For retail, corporate, hospitality and commercial spaces that prioritise both design and security, the DBGLS150 offers a practical compromise between aesthetics and access control functionality.
Before purchasing or specifying the DBGLS150, confirm glass thickness, clarify whether fail‑safe operation meets local egress and fire code requirements, and plan for any auxiliary brackets or battery backup if required. When installed by a qualified technician and integrated correctly into an access control system, the DBGLS150 delivers reliable performance, long service life and an unobtrusive appearance — making it a compelling choice for modern frameless glass door installations.
