Overview: The document is a product sheet for the Kenter Shackle, produced by Damen Anchor & Chain Factory, a member of the Damen Shipyards Group. It provides detailed specifications and load capacities for various sizes of Kenter Shackles.

Specifications: The product sheet lists the dimensions of Kenter Shackles in millimeters, including size (d), L1, P4, W4, and K. Sizes range from 12.5 mm to 162 mm, with corresponding dimensions provided for each size.

Load Capacities: The document details proof load and break load capacities for different grades of shackles (Grades 1, 2, and 3). The load capacities are specified in kilonewtons (kN) and vary according to the chain diameter. For example, a 12.5 mm chain has a Grade 1 proof load of 46 kN and a break load of 66 kN, while a 162 mm chain has a Grade 1 proof load of 5590 kN and a break load of 7990 kN.

Grades: The shackles are categorized into three grades, with Grade 3 offering the highest load capacities. The document provides a comprehensive table showing the proof and break loads for each grade across different chain diameters.

Key Data: The tables in the document provide critical data for selecting the appropriate shackle size and grade based on the required load capacity and chain diameter. This information is essential for ensuring safety and performance in marine applications.
