Sink Setter Bracket for Solid Surface Undermount Installs
The Precision Works PW-99 Sink Setter Bracket is an installation support bracket designed to hold an undermount sink in position beneath a solid surface countertop while the adhesive or silicone cures. It adjusts to fit sink openings from 14 to 26 inches, covering the range of single-bowl and most double-bowl undermount sinks found in residential and light commercial work.
Key Features
• Adjustable 14- to 26-inch range fits a wide variety of undermount sink widths without additional hardware.
• Solid surface compatibility makes it the right tool for laminate and solid surface countertop fabrication workflows.
• Bracket positioning design holds the sink flush against the underside of the countertop while the bond sets.
• Reusable construction lets fabricators install sink after sink without repurchasing supports for each job.
Where It Fits in the Install
Getting an undermount sink to sit flush and stay there while adhesive cures is one of the more frustrating steps in a countertop fabrication. Without proper support, the sink can sag, shift, or pull away from the substrate before the bond has a chance to set. The PW-99 bracket solves that problem by acting as a temporary hold-down, keeping the bowl firmly in contact with the underside of the countertop from the moment you position it until the bond or silicone has fully cured. Once the install is set, the bracket comes off and goes back in the tool kit for the next job.
Its 14- to 26-inch adjustment range makes it practical across a single job site where multiple sink sizes might be in play, from a compact prep sink to a full-size kitchen bowl.
Built for Fabrication Shop Conditions
The PW-99 is manufactured by Precision Works and sized for the undermount sink installations common in solid surface fabrication. It is a purpose-built positioning tool rather than a permanent fastening component. The bracket's function is mechanical support during the curing window, complementing the adhesive or silicone system used for the actual bond. It does not replace clips, fasteners, or the seam adhesive required for a finished install.
Who Reaches for This Bracket
Solid surface fabricators who regularly install undermount sinks will get the most out of the PW-99. It is a practical addition to any shop that handles kitchen or bathroom countertop work and wants a repeatable, hands-free way to hold sinks in position during cure. Cabinet shops moving into countertop fabrication and countertop crews who want to reduce the improvised-support workarounds that slow down an install will find it earns its place in the workflow.
Frequently Asked Questions
Does this bracket work with both laminate and solid surface countertops?
The PW-99 is specified for solid surface installations. For laminate countertop applications, confirm the bracket suits the fabrication method before using it in that workflow.
Is the bracket a permanent part of the sink installation?
No. It is a temporary positioning tool used during the cure window. Once the adhesive or silicone has set and the sink is secured by its permanent fastening system, the bracket is removed and reused on the next job.
Does it ship with fasteners or mounting hardware?
The source data does not confirm included fasteners for this bracket. Check the product's spec block or contact the sales team to confirm exactly what ships in the package before ordering.
What is the maximum sink width this bracket supports?
The bracket adjusts to support sink openings up to 26 inches wide. The minimum opening it accommodates is 14 inches.
One Less Variable on Every Undermount Install
A solid undermount install depends on more than good adhesive: the sink has to stay exactly where you put it while the bond does its work. The PW-99 takes that variable off the table, so fabricators can move on to the next step without babysitting the sink.
