Left Side BaseAce Baseboard Spacer Tool for Consistent Trim Spacing

Key features

• Consisten Spacing Every Time - Achieve professional results with uniform gaps for your trim. This baseboard spacer tool props baseboards at a precise height (fixed 3/4″ or 1/2″) so you can install with confidence. No more guesswork or uneven baseboard gaps – just perfectly level baseboard trim spacers for a clean finish.
• Hands-Free Installation - Free up your hands and work solo with ease. Baseboard spacers (2-pack) securely hold your molding or door trim in place while you nail or screw it down. Like having an extra set of hands, the BaseAce keeps baseboards steady and aligned, making one-person installations and adjustments a breeze.
• Multi-Purpose Versatility - One tool for many jobs. Use it as a spacer for baseboards, door frames, wainscoting panels, or as flooring spacers when laying laminate. The built-in 1/4″ and 1/8″ tongue tips double as laminate flooring spacers for maintaining expansion gaps, and even serve as a handy drywall spacer to lift sheetrock off the floor during installation.
• Durabe & Compact Design - Built tough for everyday carpentry. Made from high-strength lightweight material, each spacer block supports heavy trim without bending or crushing (unlike a wood shim). The compact 1.5″ × 0.75″ × 0.75″ size slips into any tool pouch. Take these spacer blocks anywhere – they’re small in your pocket but big on making installations easier.
• Designed for DIYers and PROS - Carpentry spacer tool engineered for both enthusiasts and professionals. Prosumer DIYers will love how it takes the stress out of trim work, and seasoned carpenters can speed up jobs with consistent, code-ready results. Tackle baseboard installation, door trim, and molding projects with a casual confidence – your work will look like it was done by a pro every time.

Say goodbye to shimming trim with random scraps, the BaseAce by Left Side makes baseboard and molding installs simple, precise and frustration free. This 2 pack baseboard spacer tool creates a perfect gap under baseboards, paneling or door trim every time. Just set the durable blocks on the floor, rest your trim on top and you’ve got a consistent 3/4" or 1/2" space, no guesswork, no uneven gaps, like having an extra hand on the job. Each block also features tongue tips at 1/4" and 1/8", perfect for extra tasks. Laying laminate floors? Use the tips as spacers to maintain the proper expansion gap. Hanging drywall?
