Replace skylight handles with loop that works with long handle pole

Current skylights approx 15 yrs old in kitchen and require standing on chair to operate. Handle has a #10 on the underside of the stem and the #s 9456-2C just below the hole that attaches to the post on the window. Couldn't find any brand identifiers. I measured the opening that attaches to the post as 3/8". Current handles do work. Thanks for any help you can provide.
