4" Bolt-On Winch. Similar in function to the weld-on version, this winch also accommodates a 4-inch wide strap but differs in its method of attachment. It is bolted onto the vehicle's frame or side rail, allowing for flexibility in placement and the possibility of removal or repositioning as needed. This type can be more versatile than the weld-on variant, as it can be adjusted or removed depending on the requirements of the load or the user's preference.
