QARL, HARL and DARL

[rolfw]

Having to replace a 24" actuator on a system I installed quite a few years ago, as the existing one hasn't been used in five years and won't move. as a matter of interest, I've seen the above letters used in describing different types and can't seem to find if they actually stand for anything.

I know H is Standard Duty and Q is Heavy Duty, but not sure what D is!

Edit: D is the Mini variant.

Plenty of outlets were selling stuff as the QARL motor when they were anything but.
Advertising E+OE, based on the 'HQ' prefix - caveat emptor.

How long ago was the installation ?
Based on the corrosion, if not at a coastal town fifteen years.

Thanks guys, yes, I know what the letters signify, but was wondering if the letters actually were initials as in DiSEqC, or just an arbitrary selection.

Just a guess - Acme screw, Reed sensor, Linear
