  We present the results of a deep-imaging search for wide companions to
low-mass stars and brown dwarfs using NSFCam on IRTF. We searched a sample of
132 M7-L8 dwarfs to magnitude limits of $J \sim 20.5$ and $K \sim 18.5$,
corresponding to secondary-primary mass ratios of $\sim 0.5$. No companions
were found with separations between $2{\arcsec}$ to $31{\arcsec}$ ($\sim$40 AU
to $\sim$1000 AU). This null result implies a wide companion frequency below
2.3% at the 95% confidence level within the sensitivity limits of the survey.
Preliminary modeling efforts indicate that we could have detected 85% of
companions more massive than $0.05 M_{\odot}$ and 50% above $0.03 M_{\odot}$.
