Minnesota Brand #550 Coil Spring Trap
The 550-RC has an outside jaw spread of 5 1/2" and an inside jaw spread of 4 3/4".
The cast jaw face is 3/8" thick and the offset is 3/16".
Installed is a Paws-I-Trip pan system and night latch dog.
Pan tension out of the box (un-waxed) on the two coiled version runs an average of 2.1 pounds which has been found to be a very good number for a multi species trap.
Pan tension on the four coiled model runs an average of 3.1 pounds.
Tested extensively over a three year period on coyote, bobcat, red fox, grey fox, and raccoon.
This trap is fast and excellent results were obtained using it two coiled.
We do not recommend using the 4-coiled version if grey fox is your target animal.
The 550 is an excellent live market trap as well as the trap to use on a mixed species line.
Small enough for fox and tough enough for the nastiest coyote
If you are not planning on 4-coiling your MB-550-RC's Minnesota strongly recommends cutting the excess spring pins off leaving 1/2" protruding from the frame.
Minnesota personally (along with many of their customers who have used the 550) prefer underalls to pan covers for this trap.
The underalls increase the pan tension slightly resulting in full pad or foot catches and the number of snapped traps is reduced to near zero.
They have obtained excellent results on grey fox with the 2-coiled 550 and underalls.
