Abstract
A single and double bearing less block is shown and described. The blocks can be used in block and tackle applications or anywhere a mechanical advantage is needed for a line. The blocks are designed to provide a slippery surface for the lines that are being retained and which thereby allows easy adjustment without the use of bearings or moving parts. The blocks also have ears with holes through which a retainer or smaller line can be tied to help retain the line in the block when the line is not under tension. Alternatively the retainer can be inserted through the holes and can be used to secure both a lashing and the line to the blocks when the blocks are used in alternative applications.
