12x9 BOLT System with Adjustable Upper Hinge

Properly sized trim tabs improve the performance of your boat by adjusting the running angle of your vessel. Bennett Marine trim tabs help you get on plane faster, correct listing (roll), improve visibility, and increase overall efficiency and control.

Features:

  • Get on plane quickly to see over the bow
  • Increase vessel performance and efficiency
  • Correct listing (roll)
  • Adjust the boat’s attitude for changes in speed, sea conditions, and shifting weight
  • Correct porpoising (rhythmic bouncing)
  • Controls sold separately 

General guidelines for choosing a trim tab size:

In general, the widest span tabs that will fit on the transom will be the most effective. The greater the surface area, the greater the lift. We‘ll typically recommend a 9” chord tab, but depending on available transom space a shorter or longer chord tab, or specially shaped tabs with upfins or dropfins may be advised.

As a general rule for boats with max speeds of 40MPH, choose at least one inch of trim tab span (per side) for every foot of boat length. For example, a 22′ boat would use a 24”x9”.
For speeds 40MPH and over, we’ll generally point you to one of our Performance, or Premier Line high-performance systems.

Nice shelf option
These industrial pipe shelf brackets are a great choice if you’re going for that rustic, farmhouse look. The black iron finish looks clean and modern while still giving off that classic industrial vibe. Once installed, they feel sturdy and well-built. Perfect for holding books, décor, or heavier items when paired with solid wood planks. I like the open design because it really lets whatever you’re displaying stand out. They’re also pretty versatile and work well in different spaces like living rooms, kitchens, or home offices. Just keep in mind that this is the bracket system only, so you’ll need to supply your own wood and possibly some mounting hardware depending on your setup. Overall, they’re a stylish and functional DIY option that adds a lot of character to a space.

Excellent industrial shelving hardware for the price
I bought these as a housewarming-style gift for my brother-in-law, who recently finished building an extension onto his home and finally has the space for a proper office. His family’s aesthetic leans heavily toward that cottage-meets-industrial look, and these brackets fit the brief perfectly. First impressions were excellent. The iron construction feels genuinely heavy-duty, and the machining and threading are better than I expected at this price point. The finish is a clean matte black that looks sharp without feeling overly glossy or cheap. Installation is straightforward if you’re comfortable with basic wall mounting. Because these are iron pipe components, you may find yourself making tiny adjustments with micro shims to get everything perfectly level depending on your wall and stud placement. That’s not a flaw so much as the nature of pipe-style systems. Once dialed in, though, they feel very solid. The scale is also worth mentioning. These are not subtle brackets—they’re a bit of a statement piece. That’s great if you want the shelving to become part of the room’s visual identity, but it’s something to be aware of when planning the space. One thing I actually appreciate is that they don’t include the wood shelves. Bundled wood usually drives up the cost and often isn’t the species or finish you’d want anyway. This way you can choose your own boards and tailor the look to the room—which is exactly what my brother-in-law ended up doing. Overall, a very well-executed industrial shelving system: sturdy, attractive, and surprisingly refined for the price.

Great look and storage space
I've had these shelves for two years now, and still love them. I love the industrial style. They add lots of great storage space for a small apartment. I have two sets - one for the laundry room and the other as a linen closet. Assembly is okay. Make sure you follow the instructions.
