The Pearpoint/SPX P343 500-foot reel is designed to deliver push distance when used to inspect main drains and pipes with relatively straight routes. This system is made to inspect sewers from 2 to 12 inches in diameter (12 inch with the adjustable skid). It will also go around 90-degree bends in a 6-inch pipe, as well at 45- and 33-degree bends in a 4-inch pipe. The 500-foot reel is an ideal choice for those who do not need a crawler system. 800-688-8094; www.pearpoint.com.
