These white screw inspection covers, sized at 6 (103mm), are made from high - impact polycarbonate. They come with an easy - start thread and a built - in ‘O’ ring seal for reliable performance. Quick Guide (pdf) available.

Using these screw inspection covers is easy. Simply line up the cover with the opening and start turning it using the easy - start thread. The built - in ‘O’ ring seal will ensure a tight fit. When handling these covers, be careful not to drop them as they are made of polycarbonate and could crack upon a hard impact. For maintenance, clean them with a mild soap and water solution. Avoid using abrasive cleaners as they can scratch the surface of the cover. If stored for a long time, keep them in a cool, dry place away from direct sunlight to prevent discoloration.
