SPECIFICATIONS
TRADELINE® Models
TRADELINE models are selected and packaged to provide
ease of stocking, ease of handling, and maximum
replacement value. TRADELINE model specifications are the
same as those of standard models, unless otherwise
specified. M6184D1035 and M6194D1017 are TRADELINE
models. TRADELINE models have auxiliary switch cams.
