Cleveland Controls RFS-4100-040 Switch

I don't see the dimensions listed for this switch lxwxh. Also, I see this is listed as adjustable and so will this adjust to .42 iwc? I believe it will and I see there is a thumbscrew for adjustment but are there any instructions on how to adjust this or special tools required?
