TrimMaster Tool — FAQ'S

What is the TrimMaster Tool?

The TrimMaster is a compact marking and positioning tool designed for finish carpentry — especially for installing trim (casing) around windows and doors. 
It helps you get accurate “reveals” (space between trim and jamb) without pulling out a tape measure or manually eyeballing. 

What does TrimMaster do?

• It marks the trim casing accurately by positioning the casing over the jambs and transferring marks via pre-set “tick marks.” 

• It ensures consistent reveals on all windows/doors throughout a house — no guessing or manual measuring needed. 

• It supports four standard reveal sizes: 1/8", 1/4", 3/8", and 1/2", offering flexibility for different trim styles. 

• It simplifies the work, saving time and reducing material waste compared to using tape, custom templates, or repeated measuring. 

Who is TrimMaster for? — Professionals or DIYers?

TrimMaster is built for both:

• Professional carpenters and finish-carpentry contractors who want faster, more accurate, standardized trim installations. 

• DIY homeowners doing their own door/window trims — because the tool is lightweight, compact, easy to use, and portable enough to carry in a tool pouch. 

How do I use TrimMaster?

1. Bring the casing over to the jamb (window or door).

2. Use the TrimMaster’s built-in tick-mark positions to mark the casing at the corners — no measuring tape needed. 

3. Nail off the trim following the marks to create a consistent reveal around the entire frame. 

4. Repeat for each window/door — and enjoy uniform results across all trim installations.

What size reveals can it mark?

TrimMaster supports four common reveal widths: 1/8 inch, 1/4 inch, 3/8 inch, and 1/2 inch. 

Is TrimMaster easy to carry around?

Yes. The tool is lightweight and compact — designed to fit in a carpenter’s pouch or belt — making it easy to bring along to job sites or move between different rooms. 

What if I make a mistake — is there a guarantee?

Yes. TrimMaster offers a “100% Money Back Guarantee if not satisfied.” 

What if I want to use it for both interior and exterior trim?

TrimMaster is suitable for both interior and exterior trim work (doors, windows, casings) — anywhere you need accurate reveals and clean trim installation. 

Why choose TrimMaster over traditional methods (measuring tape, manual templates, eyeballing)?

• You skip measuring, saving time and avoiding errors. 

• You get consistent, uniform reveals throughout your project, which gives a more professional finish. 

• You reduce material waste and mistakes — no need to recut or re-measure because of misaligned trim. 

• It’s faster and more efficient than building custom templates or using a combination square.
