Spin Doctor Lippage Control System – 1/8 in., Black, 250 per Box
The RTC Spin Doctor Lippage Control System 1/8 in. post is a black breakaway threaded tile leveling post, supplied 250 per box, that holds adjacent tiles flush while the mortar cures.
The post sits under two adjacent tiles with its threaded stem projecting up through the joint. A reusable cap spins down that thread until both tiles are clamped flat against one another, and once the mortar has cured the stem breaks off at the base and the cap is recovered for the next job. RTC color-codes the four sizes, and black is the 1/8 in. code.
Key Features
- 1/8 in. (3 mm) joint width — the stem sets the joint as well as the level
- Black is RTC's color code for the 1/8 in. size
- Breakaway threaded post: the stem snaps off at the base once the mortar has cured
- Screw-down system — the cap clamps by thread, with no pliers and no wedges
- 250 posts per box; a 2,000-piece bulk box of the same size is also stocked
What's Included
- 250 Spin Doctor breakaway posts, 1/8 in. (3 mm)
- Caps and Clear View Shields are not included and are ordered separately
Who Is This For?
Tile setters and floor crews running 1/8 in. (3 mm) joints who need adjacent tiles held flush while the mortar sets. The joint width is fixed by the post, so the size must match the layout.
Frequently Asked Questions
What joint does the black post set?
Black is RTC's color code for the 1/8 in. (3 mm) post, the common joint width for pressed floor tile and most wall layouts.
Do I need caps as well as posts?
The system has exactly three parts: the disposable breakaway post, the reusable red screw-down cap (SDCAP, 100 per box) and the optional Anti-Friction Clear View Shield (SDCVS). The posts and caps are bought separately, so a first order needs both.
Can I use a 1/8 in. post on a tight rectified joint?
No — the stem sets the joint, so a 1/8 in. (3 mm) post forces a 1/8 in. line. For a minimal joint use the red 1/32 in. (1 mm) post or the white 1/16 in. (1.5 mm) post.
Do lippage pliers work with these posts?
No. Pliers such as the Lippage Eliminator II are for wedge-and-clip systems, where a wedge is driven into a clip under tension. The Spin Doctor cap is threaded and is spun down by hand, so no tool is needed and pliers cannot tension it.
