RKI Explosion Proof M2A-XL Transmitter w/J-Box, cCSAus 65-264_XL-05

The RKI Explosion Proof CSA version M2A-XL Transmitter with j-box provides an alternate housing, which is slightly taller, wider and deeper, but the mounting holes, electronics and operation are the same as the original M2A housing. The slightly larger enclosure has more room inside for additional wiring. Since this housing is deeper than the original M2A, longer standoffs are required inside to properly bring the display up to the transmitter's window. Choice of LEL, O2, H2S, or CO transmitter.
