3" Heavy-Duty Gland Style Packing Box - 4-1/2" Hose

These Heavy Duty versions of Buck Algonquin's Gland Style Packing Boxes weigh approximately three times as much as their Standard Duty counterparts.

A packing box, or stuffing box, is a device that seals around the propeller shaft where it exits the vessel via the shaft log, preventing seawater from entering the boat.

Bolt, or gland, style packing boxes are preferred by many since, unlike the nut style, you don't have to swing a big wrench to disassemble them, or adjust the gland pressure.
This makes them ideal for installation in confined spaces - such as a narrow bilge.
The studs can be shortened, if desired, to allow the use of a socket wrench.

The hose connection between the packing box and the vessel's shaft log provides enough flexibility to allow for small shaft alignment discrepancies.
