Mobile Lockset Upgrade Service
Offer flat-rate, on-site installation of new knobs/levers for homeowners, HOAs, and small offices. The guided clamp speeds accurate drilling on doors from 1-3/8" to 2-3/8" thick, letting you handle retrofits, style updates, and damaged-bore fixes in one visit. Upsell strike reinforcement, new latch plates, and finish-matched hardware.
Builder/Carpenter Door Prep Add-On
Add precise, repeatable door prep to your trim and millwork packages. Pre-bore blank interior and exterior wood doors to standard backsets using the kit, reducing callbacks for misaligned hardware. Sell it as a per-door line item to spec builders, remodelers, and cabinet shops supplying custom slabs.
Short-Term Rental Smart Lock Conversion
Specialize in upgrading older wood doors to modern smart deadbolts/lever sets that require a 2-1/8-inch bore. Use the kit to correct undersized or off-center existing holes and to add fresh hardware to solid doors. Bundle programming, guest-code management, and seasonal maintenance for a recurring service fee.
Landlord Turnover Hardware Standardization
Create a fast-turn package for property managers that standardizes all unit doors to a single hardware spec. The kit lets you consistently drill accurate bores across varying door thicknesses, minimizing install time. Pair with master-keying (via a locksmith partner), door viewer installs, and strike/hinge tune-ups to increase unit security and reduce lockouts.
Creative
Reclaimed Barn Door, Modern Lock
Transform a salvaged or DIY slab door into a functional interior statement piece. After sanding and sealing the wood, use the kit’s rack-and-pinion guide to bore a perfect 2-1/8-inch cross bore and align the latch. Add a matte-black or antique-brass knob/lever with a large decorative backplate to bridge any slight surface irregularities common with reclaimed lumber. The accurate guide makes it easy to fit modern hardware into rustic material without chip-out.
Hidden Reading Nook Door
Build a shallow bookcase door that swings into a cozy nook and secure it with a simple passage or privacy set. Clamp the guide to the wood frame of the bookcase door and drill the standard lock bore so the knob or lever blends in as a ‘library pull.’ Add a magnetic touch latch behind a fake book for a playful secondary release. The kit keeps everything square even on thicker, solid-wood stiles.
Garden Gate + Shed Match-Up
Give your outdoor wood gate and shed doors a cohesive, upscale look with matching keyed levers. Use the kit to accurately place the bores so the hardware aligns with existing strike plates and keeps. Choose weather-rated locks and confirm your gate/door thickness falls within the kit’s range. The one-handed clamp makes quick work of awkward gate positions.
Home Studio Privacy Door with Custom Plate
Convert an office or studio door to a quiet, focus-friendly space with a new privacy set and a custom laser-engraved or hand-carved faceplate. The kit ensures clean, centered bores in solid wood so the custom plate sits flush and true. Pair with perimeter seals and a solid core door for extra sound control.
