RADIATOR BALANCING KEY Radiator Lockshield Valve Key All my keys are checked with a plug gauge for correct size before posting. Let me know your size - I will make it to suit your valve!! YOU must measure and make your selection, I cannot do it for you. 3D Printed, this radiator balancing tool/key fits the new "flat tab" lockshield valve nicely and makes adjusting to balance your radiators much MUCH easier! NOTE :- This will NOT free up seized lockshield valves!! It is very strong but is not designed to free up anything that is seized! If your tap is seized, replace it before using this tool! Feel free to test though - buy 2 and try to destroy 1! It's not easy!! Once you have measured your valve carefully and selected the corresponding size from the drop-down to suit, this tool will fit the tab on your chosen size valves. If the size you need is not listed, get in touch, I can do it for you. Simply measure your tab width and select your size from the dropdown. You MUST measure your valve though - I cannot do it from here!! Select your quantity and I'll get them sent out to you. Note, the standard key has lugs that are 50mm across. There is 1 key (at the moment) that will fit into a 30mm gap. Its lugs only measure 30mm across. Check out the photos for comparison. If you need a size not listed - get in touch!!!!! You can see in the photos the type of valve it fits. You will get your key in whatever I have running on the machine at the time. Normally green, orange, red or white. If you need a specific colour, let me know, I'll use it if I have it. NOTE :- This will NOT free up seized lockshield valves!! It is very strong but is not designed to free up anything that is seized! If your tap is seized, replace it before using this tool! My aim is for you to be 100% satisfied. If you are not completely satisfied with your purchase please do not hesitate to contact me; I will do my very best to resolve any issues. Please, please, please - it is YOUR responsibility to order the correct size key! I can not tell you what size your key is by looking at a photo of your valve! YOU need to measure and confirm. All my keys are checked with a plug gauge before posting.
