Sea-Dog Heavy-Duty Clamp-On Oarlock (MPN 582070-1) is a zinc-plated steel oarlock designed to secure oars 3/4 to 1-1/2 inches in diameter. It provides a stable bolted clamp mounting and a straight 2 inch long shank so you can row or maneuver without the oar slipping or the mount bending.

If you encounter loose pivots or mismatched oar diameters this clamp-on oarlock addresses those issues by using an adjustable bolted clamp that accommodates a wide range of shafts and withstands typical rowing loads. The zinc plating and heavy-gauge steel construction are recommended for freshwater applications where they resist wear and deformation.

• Adjustable bolted clamp fits 3/4 to 1-1/2 in oars
• Straight 2 in long shank for reliable oar clearance
• Heavy-gauge zinc-plated steel construction for strength
• Shank diameter options 1/2 in or 9/16 in to match fittings
• Tool-installable clamp requires no permanent hull modification

Use this oarlock on dinghies tenders and small utility boats where a removable clamp-on mounting is preferred. Compared to molded plastic or press-fit oarlocks this steel clamp maintains alignment and resists bending under heavier use.

Manufactured by Sea-Dog and listed as part number 582070-1 this oarlock is intended for freshwater use; for regular saltwater exposure choose a stainless or marine-grade alternative. Measure your oar shaft diameter to confirm fit and select the matching shank size for reliable performance. Learn more today.
