Insulator Link Fittings

DB Series Multi-Hole Adjustment Plates | DB-7 to DB-64

Product Overview

The photos and line drawing show a plate with multiple connection holes. The existing DB-series catalogue table lists DB-7 to DB-64 designations with Φ, R1–R6 and b dimensions; not every dimension column is populated for every row. Select by the mating fitting, hole pattern and approved assembly drawing.

Product Details

The photos and table do not establish steel grade, galvanizing process, socket compatibility, mechanical strength or corrosion performance. Confirm material, finish, connection hardware, load rating and required tests for the ordered model. The table is catalogue information, not a batch certificate.

Product Features

Multi-hole plate geometry is visible in the product photos and line drawing. The existing DB-series table provides model-specific dimensions; verify hole spacing, mating hardware, material and load with the selected drawing.
