Overview

This document is a technical drawing and specification sheet for Ocean LED Ltd.'s flush mount products, specifically models 1520, 2010, and 3010. It provides detailed dimensional data, mounting requirements, material specifications, and manufacturing tolerances.

Dimensions and Mounting Specifications

• Flush mount diameters and hull thickness limits are specified for different models: 1520, 2010, and 3010.
• Key dimensions include diameters ranging from 100 mm (4") to 190 mm (7.5"), mounting hole sizes (e.g., 66 mm / 2.625", 83 mm / 3.25", 108 mm / 4.25"), and maximum hull thicknesses.
• An optional Delrin isolating sleeve is available for use on metal hulls to prevent galvanic corrosion, compatible with all models.

Geometric and Manufacturing Tolerances

• Geometric characteristic symbols are defined for cylindricity, roundness, flatness, straightness, angularity, squareness, symmetry, parallelism, and concentricity.
• Tolerances on machined dimensions are ±0.05 mm for two decimal places and ±0.1 mm for basic dimensions.
• Tolerances on castings and unmachined parts are ±0.8 mm.
• Angles have a tolerance of ±0.5 degrees.
• Chamfers and edge breaks are specified: all sharp edges to be broken between 0.1 to 0.5 mm, and unspecified chamfers to be 1 x 45°.

Material and Finish

• Material specifications and heat treatment details are referenced but not explicitly detailed in the excerpt.
• Surface finish and profile run tolerances are indicated.

General Notes and Legal Information

• All dimensions are in millimeters.
• The drawing uses third angle projection.
• Reproduction or use of the drawing without written consent from Ocean LED Ltd. is prohibited.
• Contact information for Ocean LED Ltd. is provided for inquiries.

Critical Information

• Ensure hull thickness does not exceed maximum specified values for each model to guarantee proper flush mount installation.
• Use Delrin isolating sleeves on metal hulls to avoid corrosion issues.
• Adhere strictly to specified tolerances to maintain product integrity and fit.
• Break all sharp edges and apply chamfers as specified to ensure safety and proper assembly.
