Hi Chip,
Yes, I have installed the Roeger hook on a DG-300. Rather simple
device where a post on the canopy, captures a spring on the fuselage
side and keeps the rear of the canopy in place until the forward end
is up and away. Genesis has a fiberglass sleve that goes forward and
up around the rear canopy rail to do the same job, although I'm not
all that clear on just how it works. I do believe these type devices
are a good thing, I know of a bail-out from an LS-3a where the canopy
somehow rotated 90 degrees and momentarily trapped the pilots arm
against the wing. After it (the canopy) departed, the pilot released
the seat belt and while checking for the D ring, accidently pulled it
and was extracted from the seat by the deploying chute. Landed without
a scratch, some people just live right.

Has anyone installed a Roeger hook or similar device (DG offers a
spring-loaded pin that is supposed to accomplish the same thing for
older DG and LS gliders) on an older glider? The recent thread on
helmets made reference to the known danger of the canopy hitting the
pilot in the head in the event of jettisoning a front-hinged canopy in
order to bail out. The Roeger hook is designed to prevent this by
fixing the rear of the canopy so it becomes a pivot point about which
the canopy lifts off and up over the pilot in the slipstream.
