Tecnoseal TEC-BT Bennett Trim Tab Anode 95x28x14 mm – Zinc, Aluminium & Magnesium
The Tecnoseal TEC-BT series consists of rectangular sacrificial plate anodes designed for Bennett marine trim tabs. Available in zinc, aluminium and magnesium, these anodes provide replaceable sacrificial corrosion protection for compatible metallic trim tab components.
All three versions share identical dimensions of 95 mm (3.74 in) in length, 28 mm (1.10 in) in width and 14 mm (0.55 in) in height. Each anode features two mounting holes with a diameter of 6.5 mm (0.26 in), spaced 38 mm (1.50 in) centre to centre.
The models differ in material and weight: TEC-BT is zinc and weighs 0.21 kg, TEC-BTAL is aluminium and weighs 0.09 kg, and TEC-BTMG is magnesium and weighs 0.06 kg.
Important: Each anode is sold individually without mounting hardware. The listed weights refer to one anode, not a pair.

Bennett Trim Tab Application
The Tecnoseal TEC-BT series is designed for compatible Bennett trim tab installations requiring a rectangular sacrificial anode with the specified dimensions and mounting arrangement.
When installed with proper electrical contact, the sacrificial anode helps reduce galvanic corrosion of associated metallic trim tab components.
Mounting Configuration
The rectangular plate incorporates two mounting holes with a diameter of 6.5 mm and a centre-to-centre spacing of 38 mm. All three material versions use identical mounting dimensions.
Before ordering, compare the existing anode's overall dimensions and mounting arrangement with the Tecnoseal TEC-BT specifications.
Mounting screws, bolts and other hardware are not included.
Choosing the Correct Anode Material
The Tecnoseal TEC-BT series offers three sacrificial anode materials:
- Zinc: Zinc sacrificial anode version.
- Aluminium: Aluminium sacrificial anode version.
- Magnesium: Magnesium sacrificial anode version.
Material selection should follow the vessel's operating water conditions, existing cathodic protection arrangement and Bennett equipment recommendations.
Inspection and Replacement
Sacrificial anodes gradually lose material while providing galvanic corrosion protection. Periodically inspect the anode and replace it when sufficiently consumed.
For replacement selection, confirm the 95 × 28 × 14 mm plate dimensions, 38 mm mounting hole spacing and 6.5 mm mounting hole diameter.
Supply: One Tecnoseal TEC-BT series Bennett trim tab anode in the selected material, without mounting hardware.
