Core Configurations & Applications
Hardware Specifications
- Dual-Unit Magnetic Architecture: Composed of two precision-machined elements: an upright floor-mounted pillar (41.40 mm in height, with a Ø33.80 mm base and a Ø40 mm upper contact ring) and a tapered door-mounted catch (Ø34.50 mm mounting base).
- Dual-Function (Stop & Hold-Open): Acts as a solid physical barrier preventing door handles and locksets from puncturing drywall, while the integrated permanent magnet securely holds the door in an open position against natural airflow and wind drafts.
- Integrated Rubber Impact Cushioning: Equipped with a rubber buffer ring positioned on the floor pillar collar. The rubber cushions the initial door contact, preventing surface scuffing and absorbing operational sound before the magnetic catch engages.
- Concealed Fastening Design: Both the floor pillar and the door-mounted receiver feature concealed interior mounting plates, leaving no exposed screw heads on finished floors or door panels after installation.
- Surface Finish Options: Electroplated or coated in Black (B), Chrome (CR), Gold (G), Satin Nickel (SN), and Matt Chrome (MC) to coordinate with standard architectural levers, locks, and hinges.
Primary Application Environments
- Residential Homes & Apartments: Prevents doors from slamming shut due to indoor air currents in bedrooms, kitchens, and balcony entryways.
- Commercial Offices & Meeting Rooms: Holds interior doors open during business hours to facilitate free pedestrian movement while protecting partitions.
- Multi-Family Housing & Dormitories: A cost-effective, multi-functional door catch solution for volume contractor installations requiring low maintenance.
Functional Comparison: Magnetic Model DSM-100 vs. Standard Mechanical Stops
| Feature Comparison | Standard Floor Stops (DS-100 / DS-200) | Magnetic Model DSM-100 |
| Operational Role | Passive stopping deflection only | Dual-action: Physical stopping + Active hold-open retention |
| Wind & Draft Resistance | Door bounces or swings back freely | Door held firmly in place by permanent magnetic force |
| Hardware Assembly | Single floor-mounted unit | Two-piece set: Floor pillar + Door-mounted strike |
| Target Application | Basic wall and handle protection | Areas requiring hands-free open-door retention |

Frequently Asked Questions
As shown in the technical drawing, the floor pillar stands 41.40 mm high with a base diameter of Ø33.80 mm and an upper collar diameter of Ø40 mm. The matching door-mounted receiver has a base diameter of Ø34.50 mm.
When the door swings fully open, the magnetic strike plate on the door aligns with the magnetic core on the floor pillar. The magnetic attraction engages automatically, holding the door steady until a gentle manual pull releases it.
The DSM-100 is specifically designed as a magnetic catch system. For applications requiring only physical stop functionality without hold-open retention, our mechanical models (such as the DS-100, DS-101, or DS-200) are recommended.
