Horizontal Blocks
About Horizontal Blocks
Jeamar horizontal blocks are heavy-duty directional blocks designed for the most demanding applications. Utilizing Jeamar standard sheaves and welded frame, these blocks come in powder coated steel or all stainless. Stainless steel shafts and hardware are standard or ultimate corrosion resistance. Jeamar blocks have been trusted for 50 years to be a reliable cable routing solution.

Advantages of Horizontal Blocks
High Strength to Weight Design
Alloy steel sheave with machined web profile reduces unnecessary weight and provides highest strength to weight ratio.
High Sheave-to-Rope Ratio
Minimum 16:1 sheave outside diameter to rope diameter ratio to reduce rope bending stress and increase rope life.
High Working Load
Directional Blocks are rated for the full working load limit of the allowable wire rope at a 180 degree wrap angle.
High Efficiency Bearing
Sheaves utilize either ball bearings or cylindrical roller bearings for reduced friction, smooth motion, and lifetime lubrication.
