Retractable Castors Heavy Duty Castors with Lifting and Lowering Function Maximum Load of 315 kg(4 casters) for Workbenches or other Equipment

Before purchasing these I noted the range of comments from previous purchasers who specifically mentioned the positioning measurements provided by the manufacturers was incorrect. From the images you will see that I did not have the benefit of much height, such as a bench leg, to fix the castor and lifting wheels. The project was a wheeled trolley for a workshop bandsaw that I have recently purchased. I required the wheels to enable movement when elevated but when lowered they allow the base to provide a stable flat and level platform for my bandsaw, anywhere in the workshop. Therefore positioning of the wheels had to be accurate and took some effort to achieve. I also noted buyer comment regarding the manufacturer provided wood screws. In my assessment they were unsuited and not fit for, my specific purpose, therefore I replaced the countersink screws with stainless steel roundhead to support the 70kg weight of the bandsaw.The manufacture and material quality of the castor wheels and the elevating mechanism, although simple, is very good to high quality and can be fitted to suit a wide range of applications / projects, noting my comments above regarding the fitting screws and manufacturers fitting dimensions. I was able to reduce the fitting height specific to my purpose. Due to the weight considerations I considered using narrow bolts to fit to the tray, but elected not to as there are six fixing holes per wheel, more than sufficient for a wide range of project applications.Overall I am impressed by the wheels, the quality, design, materials and price make them a clear choice for a second purchase. I will use them next to fit to a large wooden bench to allow me to move it around my workshop. I have been impressed by these and highly recommend them for all the reasons stated above.

Very good, just as expected, easy to fit and use, look very solid. Fitted to a very heavy workbench which they lifted no problem, it is no easy to move it around my workshop.

Really good quality and seem really strong

Work really well. I've got them on a rather heavy workbench. Only challenge is letting them down again, where the weight of the bench results in a hard landing on the floor!

I purchased this product for a heavy duty workshop table that measurers 3mx1m. The installation template guide for the screws is accurate and simple to use. The lifting and lowering function is effortless and the best I have ever used. I would highly recommend this product.

Build quality is great and easy to install. Works as expected.
