Check the mounting interface, available space and operating limits before choosing an accessory or replacement component.
Boat trailer steps
Measure tongue width and height, mounting space, boarding height and clearance around the bow, hull and winch stand. The angled-handle CTB-A and upright-handle CT-A use different arrangements; read the exact product specifications. Install and use the steps only according to the supplied instructions, on a stationary and secured trailer.

Check the individual dimensions for the angled-handle boat trailer steps and the upright-handle boat trailer steps.
Fish finder locks
Match the screw thread, gimbal bracket shape and clearance to your exact fish finder model. A brand name alone does not confirm compatibility.

Swing-away hitch adapters
Confirm a chassis-mounted 2-inch Class III/IV receiver and approval from your rack or carrier manufacturer. The NIWNIW adapter supports up to 320 lb at a loaded reach of 28 inches or less, or 230 lb above 28 inches and up to 40 inches. Reach is measured from the rack/carrier connection pin hole to the farthest point of the loaded setup. Load includes the rack, cargo and accessories.
Include the 35.2 lb adapter in the vehicle tongue-weight calculation. Observe the lowest applicable equipment limit. Check rear-door, spare-tire, bumper, exhaust and ground clearance. Not for towing, recovery, RVs, motorhomes, travel trailers, fifth wheels or bumper-only receivers. Never drive with the swing arm open.

Replacement motors
Match the original part number, voltage, horsepower, speed, rotation, control type, shaft and mounting dimensions. An ECM X13 constant-torque motor is not interchangeable with an EON ECM 2.3, 2.5 or 3.0 constant-airflow motor. A qualified technician should confirm compatibility and perform electrical installation.
Compare the 6205E ECM X13 blower motor or F0510B2944 attic fan replacement motor with your original equipment. These are different motor applications.
OBD port locks
Check the space around the diagnostic port and the access needed for servicing. Read the OBD port clearance and service-access checklist, then compare the NIWNIW OBD2 port lock with your port location.
