Product Description
The LARSEN SUPPLY CO., INC. 0-3015 is a chrome single handle bonnet nut with adjusting ring, designed for use in lavatory faucet repair applications. This component secures the faucet cartridge or stem assembly within the faucet body and allows for tension adjustment via the included adjusting ring. It is a direct service part used by plumbers and journeymen performing handle or valve repairs on Delta single-handle lavatory faucets. The chrome finish provides corrosion resistance suitable for typical sink and vanity environments. Each unit is carded for easy identification and retail or counter-sales distribution.
This bonnet nut is applied in residential and light commercial lavatory faucet repair scenarios. It is used when the existing bonnet nut is stripped, corroded, or damaged during a cartridge replacement or valve service. The part is suited for vanity sink installations where a Delta single-handle faucet requires internal component service. Plumbing supply counters and service trucks commonly stock this item as a standard repair consumable. The carded packaging makes it easy to identify at point of sale or during service calls.
