Core Configurations & Applications
Hardware Specifications
- Engineered Dimensional Architecture: Designed with an overall height of 40.20 mm and a Ø24 mm base. This vertical cylindrical stature provides a raised contact point, making it suitable for doors with higher floor undercuts or thick carpeting.
- Full-Perimeter Rubber Bumper Ring: Encased with an outer Ø31 mm thick resilient rubber ring around the upper pillar. The 360-degree rubber band absorbs door impact momentum, prevents finish marring, and dampens closing acoustic shock.
- Plastic & Rubber Composite Build: Combines lightweight, corrosion-free molded plastic with dense shock-absorbing rubber, offering a durable and cost-effective hardware solution for high-volume supply contracts.
- Concealed Single-Point Anchoring: Mounts directly into timber, tile, or concrete subfloors via a single concealed central screw through the Ø24 mm base, maintaining a clean visual installation without visible fixings.
- Architectural Finish Options: Finished in Black (B), Chrome (CR), Gold (G), Satin Nickel (SN), and Matt Chrome (MC) to coordinate with standard interior door handles, roses, and escutcheons.
Primary Application Environments
- Residential Interior Doors: Protects walls, skirting boards, and furniture from handle collisions on bedroom, kitchen, and bathroom doors.
- Commercial Offices & Suites: Minimalist vertical pillar design integrates cleanly into modern office interiors with carpeted or tiled flooring.
- High-Volume Property Developments: Cost-effective door stop specification for student dormitories, multi-family apartment projects, and rental renovations.
Architectural Comparison: Cylindrical DS-200 vs. Dome Series (DS-100 / DS-101)
| Feature Comparison | Dome Series (DS-100 / DS-101) | Cylindrical Model DS-200 |
| Profile Geometry | Low-profile half-moon dome | Upright cylindrical column |
| Overall Height | Low floor clearance profile | Elevated 40.20 mm height |
| Bumper Configuration | Directional half-perimeter rubber bumper | 360-degree full-perimeter rubber ring (Ø31 mm) |
| Door Undercut Suitability | Best for tight floor clearances (<15 mm) | Accommodates standard to higher floor undercuts |
