It is the same width as the Losmandy Plates 4". Doesn't BT make a
longer plate than 11 1/2 inches?

Thanks Mal,

It's hard to tell much from your website, one tiny picture and no
specifications but it doesn't look like your 17" sliding bar would

be

wide enough to accomodate the 4" (approx) hole spacing for the Tak

rings.

If you look here you will see how the plate needs to be flared to
accomodate the holes...

I have the Tak-02dp (second pic from bottom - mouse over to see it
with rings attached) and it is perfect except for being too short

at

about 11 1/5" overall length.

If you can provide a similar but 17" bar predrilled to accept the

Tak

rings as shown then let me know.

Thanks
Gary

Hi,

I have a dovetail sliding bar from BT Technologies which is

about

11.5"

in total length to go on my DOVELM16S which has 11" centers

for

the

screw clamps. Obviously no good. The clamps barely grip the

plate

and

there is no overhang to allow the use of a safety screw. Not

good.

My choices are to either find a longer sliding bar drilled for

Tak

rings

(TOA-150) or to buy a shorter saddle plate which can

accommodate

the 11"

plate.

The TOA is quite heavy and with guidescope, camera, holy hand

grenade

etc the weight will probably approach 60 or 65 lbs.

Is the 8.5" plate (AP part number DOVELM2) going to be up to

this

task?

Anyone hanging this kind of weight off one?

thanks
Gary
