Whether you are trying to keep your toddler from opening the basement door, adding an attractive and functional enhancement to your closet doors or securing cabinets in your RV, the Prime-Line surface bolt is the versatile locking solution. Easy to install and constructed of durable solid brass, the 4 inch long surface bolt can be mounted horizontally or vertically and includes a surface mount keeper and a mortise-style keeper to accommodate a variety of applications. With a bronze finish, the surface bolt is not only effective, it's attractive too. It's a great alternative to traditional child (and pet) proofing products that can be hard to install and not complementary to your home decor. You can install the surface bolt out of the reach of curious little hands, so babies, toddlers and young kids cannot enter or exit into dangerous areas or go through cabinets and closets without supervision.
