Core Configurations & Applications
Hardware Specifications
- Extended 110 mm Standoff Projection: Designed with an overall length of 110 mm, ensuring ample standoff distance to prevent protruding levers, panic exit bars, or coat hooks from colliding with adjacent walls.
- 25 mm Telescopic Spring Damping Stroke: Equipped with an internal compression spring assembly that provides 25 mm of progressive travel. When the swinging door impacts the plunger, the spring compresses steadily to absorb momentum, preventing sudden rebound shock.
- Ø22 mm Rubber Bumper & Ø35 mm Strike Plate: The spring-loaded plunger tip features a non-marking Ø22 mm rubber cap that engages the included Ø35 mm circular strike disc, ensuring quiet operation and protecting finished door surfaces from scuffs.
- Robust Ø45 mm Flanged Base: Anchors firmly through a flared Ø45 mm mounting flange, providing a broad footprint that distributes shear and bending forces securely into floors or skirting frames.
- Architectural Finish Options: Electroplated or coated in Black (B), Chrome (CR), Gold (G), Satin Nickel (SN), and Matt Chrome (MC) to coordinate with standard architectural locksets and door hinges.
Primary Application Environments
- Under-Door & Skirting Installations: Mounted near the bottom edge of doors or along low skirting boards to act as a resilient mechanical stop.
- Commercial Offices & Hospitality: Protects heavy timber and hollow-metal interior doors from forceful swinging caused by wind gusts or heavy foot traffic.
- Residential & Multi-Family Housing: A practical, cost-effective door buffer providing silent, progressive door deceleration for bedrooms, hallways, and utility rooms.
Engineering Comparison: Spring Model DSS-100 vs. Static Stops
| Feature Comparison | Static Floor Stops (DS-100 / DS-200) | Magnetic Catch (DSM-100) | Spring Stop Model DSS-100 |
| Damping Type | Static rubber impact only | Static rubber + Magnetic hold | Dynamic 25 mm spring compression |
| Projection Length | Compact (40.20 mm / Dome height) | Compact pillar (41.40 mm) | Extended standoff (110 mm) |
| Impact Absorption | Abrupt deceleration on contact | Immediate catch retention | Progressive deceleration via internal spring |
| Primary Advantage | Low profile, minimal floor footprint | Hands-free open door holding | High standoff clearance & cushioned rebound |

Frequently Asked Questions
As shown in the technical drawing, the overall length is 110 mm, the telescopic spring compression stroke is 25 mm, the flanged mounting base is Ø45 mm, the main body shaft is Ø18 mm, the plunger bumper tip is Ø22 mm, and the accompanying strike plate disc is Ø35 mm.
Unlike a rigid door stop that halts the door abruptly, the DSS-100 incorporates an internal compression spring. Upon door impact, the plunger retracts smoothly up to 25 mm, absorbing the kinetic energy of the door gradually before coming to a complete stop.
The unit can be finished in Black (B), Chrome (CR), Gold (G), Satin Nickel (SN), and Matt Chrome (MC), matching standard interior door hardware suites.
