Stainless Steel Thru-Hull Standard Straight Barbed - 1" Inner Diameter

Polish your image with these beautiful, durable stainless steel fittings. Why specify plastic parts when these fittings will last the life of the boat?

Rugged Stainless Construction:

  • Cast from certified Enhanced 316 Stainless Steel alloy for strength and lifetime corrosion-resistance
  • All visible areas are polished to a mirror finish, then passivate each part for additional protection

  • Each Thru-Hull is available with a new silicone gasket
  • A channel under the flange holds a bead of sealant, making it easier to apply a trouble-free seal

Cheap and does the job
Size: 6 Feet
Seems to be well constructed, it’s a little thinner than I expected, but it passes bass just fine to my SVS PB 2000 Pro.

Great value for high quality lights
Size: 2Pcs 7.6Inch Light Bar
These are really nice lights. Night and day difference between these and the cheap Nilights. They should really try to differentiate these in their listings. Nice consistent beam pattern and color. High quality build. Power output close to claimed rating.
