Like this? There are several sites you can check out. Some rails are hard-wired and some are plug-in. Different finishes. Not all have the hooks you refer to, but some very nice styles available. This is the only one with hooks that quickly popped up on initial search. Best wishes.

the heated floor can be installed like an extra thin electric blanket under new tiles (or carpet or timber etc) and we have a portable small electric plug in floor mat under a rug in a study ...not really suitable for a quick heat but ideal for a cold place where the inbuilt timers warms up the floor to suit early morning and late evening and suprisingly cheap to buy but not cheap to run for big rooms .. we live in a cold climate and have underfloor heating under tiles in bathrooms, laundry and mudroom, under fitted carpet down a long hallway and under a loose floor mat to keep feet warm while sitting at a desk in the study and its excellent..... usually available from tile shops and on line suppliers in a range of suitable sizes including by the square metre and installed by tilers and electrician after new waterproofing and before tiles...i think the last time we installed the underfloor heating for a modest sized bathroom was well under $1000 including installation and well worth the cost

A professional installer will pack out the top fittings if needed.
