Use the ORIGINAL Wet Noodle Retriever System from Labor Saving Devices! It provides a quick and easy solution for in-wall blind wire pulling. LSDI developed the ball chain and magnetic retriever concept many years ago to help save installation time. Since its conception, it immediately became a must-have tool for retrofit installations. Here’s how to use the Wet Noodle: Create a small hole for an entry point up on the wall (the Wet Noodle works best in uninsulated walls) and drill a small hole at the bottom directly below (1/4 in. hole for the small magnet end or 3/8 in. for the bigger end). Drop the Wet Noodle ball chain down, giving it a slight jiggle to make sure it finds the bottom plate. In most cases you will “catch” the ball chain by just putting the magnet end(s) into the bottom hole. If necessary, bend the flexible retriever into an S shape to get into the wall for more difficult retrievals. Slowly pull the ball chain to just inside the bottom hole. Using the pocket retriever, hook the ball chain and bring it out the bottom hole. Please note this works best in uninsulated walls. _ • Kit includes • 10-ft. lightweight ball chain with stop ring and connectors • 1,000 ft. roll ball chain • 24-in. flexible noodle retriever with magnets on each end • 18 in. extendable pocket retriever • Provides quick and easy solution for in-wall blind wire pulling • Ideal for retrofit installations • Best if used in uninsulated walls Product Dimensions: 12 x 0.5 x 0.5 in., 0.2 lbs.
