Lifting manhole cover - which key to use?

[spiidey]

Need to lift the manholes shown in the attached pics - which is the correct key to do this, and how many of each key do I need to lift one manhole?

Would prefer a key from B&Q / Screwfix if possible so we don't have to wait for an online order.

Eyes of the manhole cover and 4.5cm long (rectangular bit) and 2.5cm wide (circular bit).

You need 4 "T" keys of suitable size, these enter the hole and turn 90 degrees. Depending on how long they have been there you may have trouble lifting them, sometimes a tap all round with a hammer will loosen them but if not you may need to hire a lifter.

Nothing online seems to really help us identify whether a key is suitable or not!

Check out Toolstation 47875.......it's a good idea to get a spade edge around the rim too.
