INCREDIBLY EASY TO SET UP - The Tumbo trolley comes with all components needed for a fast and easy 1 person set up. Our pre-looped cable is easy to attach to a secure connection point and then quickly sets up on the opposite side with our ratchet action tensioning device for a super tight non-sagging line without any cable cutting or hard to use U-bolts. | ANTI-SHOCK COILED LEAD LINE – Our Plastic-coated galvanized steel coiled cable is not only tough with an over 900 lb breaking strength it also offers the safety factor of anti-shock to help your dog with a softer slow down at the end of the line versus a harsh tug of a standard cable or chain. | LESS TANGLING – Our coiled lead line offers more tangle free roaming time while constantly extending and retracting as your dog travels allowing it to avoid being wrapped around any obstacles that may be present. This is especially helpful while at home in the backyard around patio chairs, fire pits, barbecues and other outdoor items. | EXCLUSIVE SOLID ALUMINUM SLIDER – Our unique to Tumbo smooth gliding aluminum slider replaces the standard pulley found on most overhead dog trolley tie outs that typically rust or start binding up at some point during their life. Our slider does exactly that, slides and glides along the cable for effortless movement along the length of the line and can not ever bind up. | TOUGH QUALITY COMPONENTS – All of our hard parts are either galvanized steel, nickel plated steel or aluminum/stainless steel. All of this adds up to years of trouble free and corrosion free use. The Tumbo Trolley is something that has been designed to be bought for life, a quality that is often lost on today’s cheaply made disposable products.
