• 【Adjustable Design】Engineered for precision, our undermount sink brackets feature a micro-threaded screw system enabling millimeter-level height adjustments (up to 4.3cm/1.7in). This accommodates sinks of varying depths, particularly in narrow cabinets where clearance is under 6.35cm/2.5in. The star knob ensures effortless tuning without tools, while the sink support bracket’s rubberized base prevents cabinet scratches. Undermount sink clips integrate felt padding to protect porcelain surfaces, and the under sink mounting brackets distribute weight evenly. Ideal for bathroom sink undermount or kitchen setups.
• 【Damage-Free Installation】Eliminate costly reinstalls with our undermount sink support system. The sink mount uses wall-mounted brackets that leverage cabinet walls, avoiding pipe removal. Undermount sink mounting brackets clamp tightly via flat-bottom screws and expansion tubes (included), securing sink undermount installations without countertop stress. Under counter sink support components include 16 long/short black screws for versatile mounting points. The non-slip rubber pads and sink bracket for porcelain design ensure zero surface damage during setup.
• 【Space-Saving Structure】Maximize cabinet utility with undermount sink support brackets featuring a compact triangular frame (11.4x6.4x4.2cm/4.5x2.5x1.65in). This under sink support system fits tight spaces below single/double basins, using vertical walls instead of floor space. The undermount kitchen sink brackets stabilize up to 136kg/300lbs, preventing sway even when sinks are full. Sink support requires only 5cm/2in clearance, freeing room for plumbing or storage. Includes 4 bowl-shaped supports for direct undermount sink contact.
