The tuBlug™ is the answer for those who want to Barlow-collimate their primary from the back of the scope, but have a solid tube Newtonian, or can't be bothered to slide their shroud up.
The Howie Glatter Tublug is a great product and one that has significant advantages over the BLUG:

First, the Tublug places the return shadow of the reinforcement tab
at a very convenient, easy-to-see location OUTSIDE the focuser rather
than at the inside of the focuser requiring you to peer between the
truss poles in order to see the shadow. (Of course, the BLUG is not very
useful at all with "solid tube" dobsonians!)
Secondly, many people
are a bit cautious about having to insert the BLUG into the inside of
the focuser since there is always the remote possibility that you may
drop it onto your primary mirror while attempting to insert it into
place.

For these reasons many "truss pole" dobsonian owners choose to go
with the Tubllug. the only disadvantage to the Tublug is that iit will
force you to part with a little bit more of your hard-earned savings!

The tuBlug™ is the answer for those who want to
Barlow-collimate their primary from the back of the scope, but have a
solid tube Newtonian, or can't be bothered to slide their shroud up.

It's a Blug (Barlowed laser plug), containing its own lens and shadow
screen that fits within a side cut-out tube, the combination being
known as a tuBlug. Like the collimator self-Barlow attachment or the
Blug, it uses the Barlowed laser principle to project a silhouette
shadow of the primary mirror collimation mark back onto its white
screen, where the shadow is centered to collimate the primary. The
tuBlug comes in 1¼" and 2" sizes, fits any focuser, and can be used with
any well-centered laser collimator.

Unfortunately, the standard Blug which fits to the inner end of the focuser drawtube inside the
telescope, can not used as a tuBlug because it must necessarily have a
shoulder which will seat it squarely against the end of the drawtube.
The shoulder will be larger than eyepiece diameter, which will prevent
the Blug from fitting in the side cut-out tube.

* Use with a regular laser collimator in single beam mode to perform
barlowed laser Newtonian primary mirror alignment on closed tube
reflectors.

* The Howie Glatter TuBLUG is inserted into the focuser tube and does not attach to the collimator,

* Rubber O-ring retainment base, matte-white 45 degree face and
anti-reflection coated Barlow lens mounted in a central axial hole.

* The Howie Glatter TuBLUG is easily visible from primary adjustment
position and can be turned 180 degrees to face the front and has a
cut-out.
