This frame features a 2.5-inch double rail center brace and full-length siderails. Four modification plates allow for a secure connection to hook-on headboards and footboard. The plates can be micro adjusted to accommodate virtually any headboard/footboard, and adjustable-height glide feet provide custom support for any bed.
