Our Homeowner Series Poles utilize the same locking mechanisms that many pool professionals use on a daily bases all over the United States. All homeowner poles are thinner and lighter than our service poles but still have the High Quality 100% USA Made Materials. This line was made for the homeowners who are looking for better equipment and are sick of wasting money for low quality products typically sold at box stores. The External Lock has been an staple in the industry since 1959 and is made of the strongest plastics. The Plastic male fitting is pressed onto the outside tube with a ton of pressure, so it won’t fall off. The female and ferrule fittings are easily replaced when worn.
