GCO-04 Framed Rectangular Enhanced Aluminum Mirrors

The source lists GCO-0402M, GCO-0403M and GCO-0401M in the GCO-04 / GCC-1021 series. The first two cards explicitly identify framed rectangular mirrors with values of 70 × 100 and 100 × 150 respectively, without units or dimensional definitions. The third card gives only a model identity, so its dimensions remain unconfirmed. Shared photography provides a framed-mirror appearance reference, rather than evidence of a two-piece pack or the supplied GCO-0401M configuration. These descriptions keep framed and unmounted product information separate and identify optical performance, mounting interfaces and delivery configuration as items requiring model-specific confirmation. English artwork helps identify the family appearance while remaining unsuitable as an engineering drawing.

Models and dimension cards

The GCO-0402M card states rectangular, framed and 70 × 100; GCO-0403M states rectangular, framed and 100 × 150. Neither value pair has a unit or a definition identifying optic outline, clear aperture or frame dimensions. The GCO-0401M card supplies only its model. Dimensions are not borrowed from the other options or estimated from photography. Complete identities are retained without decoding the M suffix.

Frame appearance and mounting

Shared photography shows two dark rectangular frames with reflective faces, side supports and short knobs. GCO-0402M and GCO-0403M are explicitly labeled framed. GCO-0401M has only the shared framed appearance; confirm its actual supplied configuration. Photography does not establish a two-piece kit, adjustment-axis count, travel, precision, locking mechanism or mounting thread. Verify frame material, interfaces, weight and accessories against model-specific drawings.

Enhanced-aluminum coating and performance

Enhanced-aluminum mirror is the source designation, not evidence of an aluminum frame or an entirely aluminum optic. Enhancement layers, protective layers, substrate, operating band, reflectance, incidence angle, polarization and damage threshold are absent. Values from unmounted GCC-1021 mirrors are not transferred. Photographic reflections do not establish spectral performance or surface figure.

Selection, custom sizes and delivery

The source offers custom sizes without establishing additional stocked models or guaranteeing a particular custom range. Confirm model, dimension units and definitions, actual supplied frame, mounting requirements and optical conditions. The source lists 2–7 days for dispatch. Check current stock, quantity, accessories, custom-size feasibility, cleaning method and actual delivery with the supplier.
