"Purchased fully castoring hard rubber castors 39449 for a box weighing about 140 lbs, These hard rubber rollers very quickly began chipping when off carpet onto concrete and eventually broke up completely after just a few uses. Purchased 94751 next and transferred the rubber and plastic rollers over BUT although the rubber tyres are good the plastic rims break up very easily. These nylon rollers are the third attempt and have the necessary strength for coping with hard & soft surfaces"
"Straight forward set of wheels. I have made some garden fete sideshow games, a little heavy to carry. Two of this set of four wheels on each, has made a massive difference to regular moving. Small enough to be inconspicuous, but substantial to take a fair amount of weight. Great value for money, definitely recommend them to others."
