It projects both a horizontal and vertical red laser line simultaneously in cross-line mode, delivering a leveling accuracy of 5\/16 inches at 30 feet across a working range of up to 50 feet. Power options include standard AA batteries or an optional 3.7-volt Lithium-Ion 1.0 Ah battery that supports use while charging. The unit carries an IP 55 rating for dust and water resistance, making it suitable for demanding site conditions. Electricians, plumbers, tile setters, and general contractors are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThe GLL50-20 is suited for interior finish work, mechanical rough-in layout, partition framing, and fixture alignment in both residential and light commercial settings. The cross-line projection allows a single technician to establish level and plumb references simultaneously without a second set of hands. Tilting the unit manually disengages the leveling mode so lines can be projected at custom angles, expanding its use for stair stringers, sloped soffits, or angled installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e50-foot working range with 5\/16-inch leveling accuracy at 30 feet\u003c\/li\u003e\n  \u003cli\u003eProjects simultaneous horizontal and vertical red laser lines in cross-line mode\u003c\/li\u003e\n  \u003cli\u003eSmart Pendulum System self-levels and blinks to indicate out-of-level conditions\u003c\/li\u003e\n  \u003cli\u003ePendulum locks automatically when switched off for safe, secure transport\u003c\/li\u003e\n  \u003cli\u003eIP 55 dust and water-resistant rating for use in demanding environments\u003c\/li\u003e\n  \u003cli\u003eFull rubber overmold housing protects major impact points on all sides\u003c\/li\u003e\n  \u003cli\u003eCompatible with AA batteries or optional 3.7-volt Lithium-Ion 1.0 Ah battery\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use as a freestanding cross-line laser on standard tripods and compatible mounting surfaces.

Before use, ensure the mounting surface or tripod is stable and rated for the unit weight. Power down or remove batteries before transporting the unit to prevent pendulum damage. Verify the leveling indicator is steady and not blinking before recording any reference lines.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWorking Range\u003c\/strong\u003e: 50 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLeveling Accuracy\u003c\/strong\u003e: 5\/16 inches at 30 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLaser Line Modes\u003c\/strong\u003e: Horizontal, Vertical, Cross-Line\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBattery Type\u003c\/strong\u003e: AA (included); 3.7-volt Lithium-Ion 1.0 Ah (sold separately)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIP Rating\u003c\/strong\u003e: IP 55 (dust and water resistant)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9.39 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ROBERT BOSCH TOOL GROUP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: GLL50-20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BOSCH","offers":[{"title":"Default Title","offer_id":51562601480498,"sku":"GLL50-20","price":1333.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/32585ba73b099f550fd4df3cae0e9c2b.jpg?v=1786480552","url":"https:\/\/voomisupply.com\/products\/bosch-gll50-20-self-leveling-cross-line-laser-50-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
