Breadboards, Tabletops, Rails & Carriages
Holmarc's 19-inch Equipment Rack Series is engineered specifically to bridge laboratory electronic instrumentation, laser diode power supplies, motion controllers, and precision optomechanical assemblies. Built with heavy-gauge extruded aluminum vertical uprights and high-tensile steel base plates, these open-frame bays guarantee high structural rigidity, minimal torsional deflection, and effective vibration isolation. Designed in strict accordance with EIA-310 standards, they support both standard chassis and specialized internal optical breadboard shelves.
19" Equipment Rack Selection
Standard single-column open rack frames supplied complete with 2" caster wheel assembly, vertical extrusion rails, top stabilizer plate, and M8 high-tensile assembly hardware. Configurable from 12U desktop bays to 42U full-height bays.
EIA-310 Standard Precision Rails
Standard 465 mm mounting hole centers and 451 mm clear aperture ensure universal compatibility with 19" lab instruments, controllers, and rack cases.
Integrated Optical Breadboard Shelves
Specialized 2U shelf modules incorporate M6 or 1/4"-20 tapped hole matrices on 25 mm pitch for direct mounting of optics and beamlines.
Heavy-Duty 2" Swivel Casters & Levelers
Smooth-rolling 2-inch swivel caster wheels with leveling support pads (140.5 mm ground clearance) enable effortless mobility and rigid floor locking.
M8 Reinforced Column Rigidity
Dual heavy-wall vertical columns secured with high-tensile M8 bolting and corner gusset braces prevent frame deflection under heavy lab loads.
