ITERATIVE UPGRADE OF SCALE PRECISION: Delivers dual enhancement in scale readability and precision drilling positioning. With laser-calibrated edge distance scale, novices can effortlessly achieve "zero-deviation" precision for seamless installation. Equipped with 4mm universal guide and 8-inch vertical adjustment module, it fits 99% of cabinet handles/hardware, ideal for cabinet handle jig positioning needs. AEROSPACE-GRADE ANTI-CORROSION ALUMINUM STRUCTURE: Made of aerospace aluminum alloy via one-piece forging, with a military-grade anti-oxidation coating on the surface (wear resistance doubled compared to traditional materials). Passes the 1000-hour salt spray test, boasts superior corrosion resistance, preventing rust and deformation. Suitable for humid kitchens, outdoor work and complex scenarios, its durability far surpasses that of ordinary cabinet hardware jig 2025 UPGRADED FOLDABLE DESIGN FOR PORTABILITY AND EFFICIENCY: Featuring an original central axis folding mechanism, it reduces to 1/3 of its expanded volume when stored, easily fitting into tool bag side pockets. The lightweight body with a high-strength pressure-resistant shell is suitable for multi-scene carrying. One tool replaces multiple positioning templates, saving 60% on tool expenses ULTRA-SIMPLE DESIGN FOR EASY OPERATION: First, loosen the central adjustment nut; then slide to position the required hole spacing; finally, lock it and start working. No professional tools or complex calibration are needed. The patented guide slot structure automatically corrects the drill bit's vertical angle, avoiding "slanted holes" and "crooked holes". Installing a single hole takes only 30 seconds, 5 times more efficient than traditional methods, reducing material loss. PROFESSIONAL TOOL FOR ALL-SCENARIO USE: Applicable to cabinets, wardrobes, bathroom cabinets, office furniture, etc., supporting the installation of various handles. Suitable for professional carpenters' batch operations or DIY home use, precise positioning can be achieved with simple adjustments. It comes standard with a universal drill guide sleeve, compatible with mainstream electric drills, realizing "one tool in hand, worry-free installation". Intelligent Adjustable Precision Positioning — Zero Deviation Every Time! Tired of guessing hole positions by feel, only to end up with lopsided handles? This jig features 6 standard hole spacings (1 inches to 3.5 inches) and a 4mm universal aperture, paired with a 6.7-inch vertical adjustment range, making it compatible with 99% of cabinet knobs, drawer pulls, and handles on the market. The edge distance scale aligns precisely with cabinet doors and drawer sides, eliminating errors from experience-based estimation. Even beginners can drill professional-grade "zero-deviation" holes, ensuring hardware fits perfectly. Aviation-Grade Aluminum Body — 10-Year Durability Guarantee Worried about flimsy tools that rust or warp easily? Our jig is made from automotive-grade lightweight aluminum, treated with anodization to enhance wear resistance by 300%, and has passed over 1,000 hours of salt spray testing. Whether in humid kitchen environments or outdoor workplaces, it remains stable and rust-free, with a service life of over 10 years—far exceeding ordinary steel clamps.
