Figure MK8. Double-longspring trapwith double-jawDouble Jaws (Figure MK8)Average Mechanical Description and AttributesInside jaw spread (at dog): 3 7 / 8 inchesInner width: 3 1 / 8 inchesInside width at jaw hinge posts: 3 7 / 16 inchesJaw width: 1 / 2 inchJaw thickness: 1 / 8 inchLength of main trap springs: 4 3 / 8 inchesThickness of main trap springs: 1 / 16 inchWidth of main trap springs: 1 1 / 2 inches narrowing to5/ 8 inchBase plate: Not reinforcedPan stop: YesAny trap that has similar specifications may be considered a BMP trap regardless ofbrand or source of modification, although performance information on all other BMPcriteria (see Introduction: “Criteria for Evaluation of Trapping Devices” pages 4-6)needs to be considered as well. The trap tested was the Sleepy Creek No. 11 doublelongspring,double-jaw trap.Additional Information• For use in submersion sets only.• Chain attachment used in trap testing: 12 inch center-mounted with three swivels,one in-line shock spring, and anchored with a stake. When using submersion sets,chain length should be short enough to prevent captured animals from resurfacing.• Selectivity features: Brass pan tension machine screw; pan tension was set so twopounds of pressure triggered the trap, and was checked and readjusted as neededafter every capture.• Special considerations for practicality: This device also meets BMP criteria forrestraining and submersion sets for river otter, and submersion sets for mink, beaverand nutria.Bodygrip Traps (Figures MK9a, MK9b, MK9c, MK9d, MK9eand MK9f)Average Mechanical Description and AttributesHeight of trap window: 4 7 / 8 inchesWidth of trap window: 4 5 / 8 inchesDiameter of frame wire: 3 / 16 inchDiameter of spring wire: 3 / 16 inchAdditional clamping bar: None, but does have a magnum bend which eliminates thegab between the jaws when the trap is closed.Safety features: Spring latchesAny trap that has similar specifications may be considered a BMP trap regardless ofbrand or source of modification, although performance information on all other BMPcriteria (see Introduction: “Criteria for Evaluation of Trapping Devices” pages 4-6)needs to be considered as well. The trap tested was the Belisle Super X 120 bodygriptrap.MUSKRAT 8Association of Fish and Wildlife Agencies
Additional Information• Safety considerations: Use of setting tongs and safety gripper is recommended.• Special considerations for practicality: This trap also meets BMP criteria for martenand fisher.Average Mechanical Description and AttributesHeight of trap window: 4 5 / 8 inchesWidth of trap window: 4 3 / 4 inchesDiameter of frame wire: 3 / 16 inchDiameter of spring wire: 3 / 16 inchAdditional clamping bar: NoneSafety features: Spring latchesMost bodygrip traps approved inthis BMP were tested via computersimulation modeling relative toanimal welfare performance.As a result, trap anchoringinformation does not exist forthese traps. However, bodygriptraps should always be securelyanchored. Anchoring informationis provided on specific traps thatwere field tested.Any trap that has similar specifications may be considered a BMP trap regardless ofbrand or source of modification, although performance information on all other BMPcriteria (see Introduction: “Criteria for Evaluation of Trapping Devices” pages 4-6)needs to be considered as well. The trap tested was the B.M.I 120 bodygrip trap.Additional Information• Safety considerations: Use of setting tongs and safety gripper is recommended.Figure MK9a.
