Unbranded Stainless Steel Weighted Baseplate Stand w/ Adjustable Arm Assembly

Unbranded Stainless Steel Weighted Baseplate Stand w/ Adjustable Arm Assembly

This is a precision-machined stainless steel weighted baseplate with an articulating two-arm assembly. The unit consists of a heavy round disc base, a central vertical post, and a horizontal arm that splits into two adjustable extensions — each terminated with a machined cylindrical end fitting. One end features a knurled cap with an O-ring seal groove; the opposite end is an open-bore cylinder. A cotter pin / spring clip on the underside of the arm provides retention or locking. The all-metal construction and weighted base design suggest use as a fixture, instrument, or probe stand in a laboratory, optical, or precision industrial setting.

Applications

Weighted baseplates with articulating arm assemblies like this one are used in laboratory, optical, semiconductor, and precision industrial environments as stable freestanding mounts for instruments, probes, sensors, or tooling. The heavy disc base provides stability on a bench or table surface without requiring fastening, while the mounting holes allow permanent bolt-down installation when needed. The knurled end fitting with O-ring suggests a fluid or gas fitting interface, or a precision clamping interface for a probe or lens assembly. This type of stand is common in cleanroom, metrology, optical alignment, and semiconductor process tooling setups where a rigid, vibration-resistant base is needed to hold a component at a fixed position relative to a workpiece or instrument.
