Are there tugnuts meant to fit forward facing horizontal dropouts such as those on a Surly Cross Check, All City Space Horse, or Salsa Cassaroll which won't block rack and fender bosses and keep wheel from sliding forward during heavy pedaling or skid stopping on fixed gear setups?

I know you didn't meant it, but no wheel properly tightened in place should slide forward, and the reason for using tugnuts shouldn't be to avoid sliding under power (but, by the way, to help positioning the wheel when tightening). –  heltonbiker Apr 24 '12 at 21:24

You can use a BMX chain tensioner, like this one, reversed, on some dropouts, but you will need to find one that works with your particular frame and dropout.

There is nothing designed for that purpose which I am aware of. However, If you are using proper torque, and proper track nuts, or nuts with washers, your wheel should not move in the dropout, with or without a tensioner.

Tensioners are designed to make it easier to align the wheel, and get proper tension on the chain, not to keep the wheel from slipping in the dropout.

If your wheel is slipping in the dropout, then there is something else wrong, in my opinion.

Putting this in the dropout reversed only prevents wheel from sliding backwards, not forwards. The chain prevents backwards movement (at least on the drive side). This cannot be setup to prevent forward movement in the dropouts due to the design, which is the typical issue due to forces puling the axle forward when pedaling or skidding (on fixed gear) –  Benzo Jan 24 at 19:56

I was able to use a surly tuggnut tensioner with my cross check frame with semi-horizontal, forward facing dropouts. No slipping after that. The end of the tensioner bolt bolt nested in the opening on the rear of the dropout where the long wheel positioner bolt would be installed. It would likely work on most bikes with this style of semi-horizontal dropout.

Looks like this:
