Tecnoseal Aluminium Slim Shaft Collar Anode Size Guide:

• Please refer to the diagram in the product photos for measurements.
• Due to current demand, this is the only aluminium shaft collar anode we keep in stock, but we can order in any size below, albeit with a slightly extended lead time. Please contact us for our most up-to-date prices and lead times if this is something you require.
• If you urgently require a salt water shaft collar anode in a different size, we recommend checking out our much wider stocking of zinc shaft collar anodes; or for fresh water, magnesium shaft collar anodes.
