The Black K Type Spider Fitting is a three-arm point-fixed glass connector engineered for corner and edge applications in modern glass facade systems. As a variant of the standard spider fitting family, the "K" configuration features two arms aligned at 180° (forming a straight line) and a third arm positioned at 90° — creating a silhouette that resembles the letter "K". This geometry makes it the ideal fitting for L-shaped glass corners, skylight ridges, and facade perimeter details where a four-way cross spider would be unnecessary or visually intrusive.
The "Black" designation refers to a premium dark surface finish — most commonly achieved through PVD (Physical Vapor Deposition) coating, black anodizing, or fluoropolymer powder coating — applied over a 304 or 316 stainless steel substrate. The black finish delivers a sleek, contemporary aesthetic while maintaining the corrosion resistance and structural integrity of stainless steel, making it a favored choice for high-end architectural projects where hardware must either recede visually or serve as a deliberate design accent.
Key Features
-
K-Profile Geometry — 180° + 90° three-arm layout purpose-built for glass corners, edges, and skylight ridges
-
Premium Black Finish — PVD black coating, black anodize, or fluorocarbon powder coat for a uniform, durable dark surface
-
Articulated Joints — Each arm independently swivels ±15° to accommodate glass deflection, thermal movement, and installation tolerances
-
Stainless Steel Core — 304 or 316 stainless steel substrate beneath the black coating for structural strength and corrosion resistance
-
High Load Capacity — Engineered to withstand wind pressure, dead load, and seismic forces per project specifications
-
Frameless Aesthetic — Minimal visible hardware; black finish further reduces visual weight, allowing glass to dominate the facade
-
Easy Maintenance — Smooth, non-porous coating resists fingerprints, water staining, and environmental soiling
-
Full Compatibility — Interchangeable with standard routels, glass holders, and supporting hardware from the same system family
| Arm Position | Angle | Function |
|---|---|---|
| Arm 1 (Horizontal Left) | 180° from Arm 2 | Secures one glass panel along the straight run |
| Arm 2 (Horizontal Right) | 180° from Arm 1 | Secures the adjacent glass panel in the same plane |
| Arm 3 (Vertical / Perpendicular) | 90° from Arms 1 & 2 | Secures the glass panel on the perpendicular face (corner) |

Vertical Standard
Contact UsThe Ringlock Scaffold verticals, also known as standards or uprights, are the vertical metal tubes that form the backbone of the RingLock scaffolding system.
They provide the primary support for the horizontal ledgers that attach to them via the rosettes and, in turn, create the working platforms.
