Review on 🔶 ROBLOCK Heavy-Duty Rubber Wheel Chocks with Reflective Tape – 4.1" x 7.8" x 3.9" – Nylon Rope – Yellow by Jeff Dabney

Not "hard" but NOT easy! Durable and rubbery, they're almost identical to those I've seen at airports and commercial docks. The rope is long enough to fit either side of a two axle tandem trailer. Not long enough to highlight two tires on opposite sides of the car at once (i.e. both rear tires). I would like to buy a second set but there is no need to grind both rear tires. even if the car is at an angle of 25 degrees! A good thing!
