Tiling a floor or wall and want those grout lines to be perfectly even?
These RTC spacers are a pro favorite for a reason.
They're the classic 'leave-in' type, meaning you don't pull them out after the mortar sets - they stay right in the grout.
The 3/16-inch size is super common for many tile jobs.
The pack has 400 pieces, which should be plenty for most bathroom or kitchen projects.
The cool feature is they're stackable - you can snap them together to make a wider spacer if you need a thicker grout line (handy for uneven tiles).
The arms are rigid and designed to hold a perfect 90-degree angle, so your tiles won't slip out of alignment.
They've been around for over 30 years, so you know they're tried and true.
Just place them at the intersections of your tiles as you work.
Simple, effective, and they make a huge difference in how professional your DIY tiling job looks.
