1-1/2" Shaft Zinc (SL-1500) Streamline Collars - Weight 1.812lbs

Highly recommend the value of this product. it's doing it's job on sailboat that is in the salt water full time. Extremely happy and will look to buy from again next time.

These are amazing so thick and if your like me who dives under the boat to install them these have screws that do not fall out!!

Bought for a use totally different than boat zincs. Way bigger and heavier than I expected. Well-built, clean, and fast delivery.
