Prime-Line U11026 Jamb Repair & Reinforcement Kit – 59-1/2 in, White Steel

Boosted door jamb durability without fuss

The Prime-Line U11026 Jamb Repair and Reinforcement Kit is designed to strengthen weak door frames by replacing vulnerable latch and deadbolt strikes. Built from steel with a white powder-coated finish, this kit adds rigidity to the critical jamb area, helping your entry system stand up to daily use and potential stress.

When fully installed, the assembly achieves up to 12 gauge thickness and spans a total height of 59-1/2 inches. The result is a sturdier, more secure doorway that remains visually unobtrusive thanks to its clean white finish that blends with most doors and jambs. The kit’s parts are paintable, making it easy to match your decor if you’re refreshing a doorway during a renovation.

What’s included and how it goes on

• Six easy-to-install section plates that reinforce the jamb at key weak spots
• Two door edge guards to protect against impact and wear along the door edge
• Three-inch fasteners (10, #8 x 3 in) for a secure, durable install
• Non-handed hardware suitable for left- or right-handed doors, single or double hinged

Installation is straightforward for DIY projects and professional upgrades alike. The kit can be surface-mounted on the door jamb if there’s a generous gap between the door edge and jamb, or mortised for a flush fit where space is tighter. The latch plate includes optional deadbolt knock-out plugs to accommodate two different knob-to-lock spacing arrangements, offering flexibility to pair with existing hardware.

Practical use cases and benefits

• Reinforces damaged or vulnerable jamb areas to improve long-term stability during everyday use
• Protects the door edge and latch region from wear, reducing the likelihood of misalignment over time
• White powder-coated steel blends with most doors and jambs, with a paintable finish for customization
• Non-handed design supports a wide range of door configurations, including different hinge arrangements

Note: Please review the line art dimensions and compare with your needs before ordering to ensure the kit meets your specific doorway configuration. This kit is intended to supplement existing hardware, not replace it, and results may vary based on door construction and installation accuracy.
