Pipe Supported Dock Pipe Caps fit over dock support pipes measuring 1-7/8 diameter. The cap is round vinyl and features a pin-sized hole in the top for ventilation. Vinyl caps protect boaters from sharp edges and prevent insects from entering the pipe. Pipe caps perform in both fresh and saltwater applications. Quantity of 6 caps per order.
Ordering Instructions: Pipe is measured on the INSIDE, whereas tubing is measured on the OUTSIDE. (A TUBE example is a chain-link fence post.) Most dock manufacturers use aluminum or steel pipe for supports and pilings so measure the diameter on the INSIDE to ensure these caps will work for your application.
