Since then more than 10,000 brackets has been produced building pens in sizes from 100 mtr to 168 mtr circumference. The HD450 was the first bracket to come with the integrated sinker tube sleeve.
Typically we recommend making the 450mm pens in sizes from 100m circumference upwards to ensure sufficient flexibility in the construction. Unique details are featured such as the front fender, sinker tube sleeve with galvanized or stainless protection and wide and heavy duty walkway panels.
Unbeatable economics makes this popular bracket a true best seller with installations in hot tropical conditions to the cold and harsh Northern Atlantic.
