Fingerboard Obstacles: Types, Sizes, and What to Look For

Obstacles are the objects a fingerboarder slides, grinds, manuals, or rolls over to link tricks. Most setups combine a few core categories.^1, 2

• 01Rails: long, thin metal pieces for slides and grinds. Sub-types include round rails, flat (square/rectangular) rails, and angled or kinked rails. Often mounted to a wood or plastic base for stability.
• 02Ledges and curbs: solid flat-topped surfaces for grinds, slides, manuals, and combos. Common materials are wood, marble/stone, concrete, and plastic. Wax ledges are surfaced or waxed for smoother slides.
• 03Ramps: transition pieces including quarter pipes, mini ramps, banks, and kickers. Quarter pipes provide a curved vertical transition; banks are straight angled inclines; kickers are small launch ramps.
• 04Manual pads: low, flat raised platforms used to practice manuals and link tricks between other obstacles.
• 05Boxes and funboxes: rectangular obstacles, sometimes with ledges or coping on the edges; funboxes combine multiple features (ledge plus rail, or ledge plus kicker) in one piece.
• 06Stairs and sets: stepped obstacles that change trick timing and are often paired with rails or ledges as a 'hubba'.

These dimensions are taken from brand product pages and authorized-retailer listings. Figures can vary slightly between listings and production runs, so sellers should measure the actual item rather than copying a spec sheet.^{3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14}

Many fingerboarders build a 'spot' on a desk, table, or shelf and session it like a small skatepark. The community shares spot photos and DIY park builds widely, and there are collaborative maps of public and DIY spots.^{1, 15, 16}

• 01A desk setup usually combines a flat riding surface with two or more obstacles arranged into lines.
• 02Obstacles are often placed parallel, staggered, or stacked so multiple tricks can be linked in one run.
• 03Riders protect the desk surface with a thin mat, cutting board, or piece of cardboard under the obstacles.
• 04The community has a strong DIY ethos, including hidden DIY fingerboard parks documented in skate media.
• 05Spot-sharing maps and groups let riders find and add real and DIY fingerboard spots.

DIY is a core part of the obstacle scene. Documented builds range from quick cardboard ramps to cast concrete ledges. Materials affect feel, durability, and how the obstacle slides.^{17, 18, 19, 1, 20, 21}

• 01Wood: maple and birch are documented as durable hardwood choices that resist warping; pine and other softwoods dent more easily. Sanding to a fine finish (e.g., 220+ grit) reduces friction.
• 02Plastic: lightweight and smooth; common for inexpensive ledges and rail bases.
• 03Metal rails: round or square steel/aluminum bar mounted to a base for grinds and slides; drawer handles are a documented improvised rail.
• 04Concrete / polymer-modified concrete: cast into ledges, banks, and kickers for a realistic feel and weight that helps pieces stay put.
• 05Cardboard: a documented low-cost starter material (e.g., a cereal box) assembled with glue and tape for ramps and banks.
• 06Tile and grout: documented for simple ledge-style obstacles, sometimes finished with grip tape for stability.
• 07Foam/grip tape and wax: used to surface or wax ledges for smoother slides ('foam tape wax' setups).
• 08Household stand-ins: textbooks add height quickly; marble trays add weight that keeps a ledge in place.
• 09Concrete-adjacent materials: Harrier is a useful reminder to verify material claims. FlatFace describes Harrier as its own long-running material and lists the category under Stone, so sellers should not flatten it into a generic concrete claim.

Several brands produce fingerboard obstacles at different price, size, material, and realism points. Brand pages are referenced here for documented facts only; no ranking, value, rarity, or authenticity claim is made.^{2, 22, 9, 8, 13, 14, 12, 10, 11, 21, 20, 23}

• 01Blackriver Ramps: German brand that describes itself as making professional wooden fingerboard obstacles, handmade in Germany; broad catalog of boxes, curbs, quarter pipes, rails, ledges, and kickers.
• 02Blackriver Concrete: official concrete category with street-reference pieces such as Parking Block, Jersey Barrier, Kink Barrier, Wallie Pylon, and ceramic/concrete transition pieces. Captured price snapshots ranged from EUR 17.95 to EUR 37.95, depending on model.
• 03Winkler ramps: Blackriver signature-ramp models (for example, Winkler Mini DOS and Winkler 80's Tribute), not a separate obstacle manufacturer.
• 04Teak Tuning: US-based brand with rails and ramps in steel, plastic, wood, and concrete, plus the hand-poured polymer-modified-concrete Monument Series.
• 05CreteDoctor: US maker with a dedicated concrete-obstacles category; captured examples include Bird Bath variants and custom concrete park obstacle commissions starting at $300 before complexity and size adjustments.
• 06YEE CONCRETE: Korean YEE Fingerboard Store line; the captured A-Barrier page lists vendor YEE CONCRETE, describes a low-height barrier, warns handmade sizes can vary, and showed a $32 price snapshot.
• 07Yellowood: Portuguese fingerboard brand whose concrete Mini wall product page documents a 30 cm-long, 800 g concrete obstacle with base stoppers.
• 08WhytMykConcrete: concrete/realistic obstacle maker represented at The Vault; retailer copy credits Mike Clarke from Huntington Beach, California and describes handmade pieces with deliberately worn-looking realism.
• 09Harrier / FlatFace: stone/concrete-adjacent obstacle material reference. FlatFace says Harrier Material was created by Harald Schoen in Germany, original since 2010, made in the USA with FlatFace in small hand batches, and completely handmade.
• 10Mini Materials: retailer/maker of concrete-style fingerboard ledges and park obstacles.
• 11ABC Parks: US (Michigan) maker of handmade fingerboard parks and ledges — birch-ply bases with painted aluminum coping and rails, modular park systems, Letter Ledges, and commissioned builds; founded by Adrian Herrera.
• 12DIY / handmade makers: a large part of the obstacle ecosystem; many obstacles are one-off builds sold within the community.

Used obstacles are durable but can develop condition issues that affect slide quality and safety of the trick surface. Check these before buying.^{17, 1, 10, 11}

• 01Warping: wood and some boards warp with moisture or heat; a warped ledge or ramp will not sit flat. Ask for a photo on a flat surface.
• 02Rail damage: bent, scratched, or loose rails grind poorly. Check that rails are straight and firmly attached to the base.
• 03Surface wear: deep gouges, chipped coping, or worn finish change how the obstacle slides.
• 04Cracks and chips: especially on concrete, brick coping, and edges of wood pieces.
• 05Concrete details: look for repaired corners, hairline cracks through thin walls, chipped coping, missing rubber feet/stoppers, and dusting or flaking sealant.
• 06Missing hardware: screws, mounting bolts, or feet that attach rails or join modular pieces.
• 07Loose joints: on funboxes and multi-part obstacles, check that sections are still tight.
• 08Stability: heavy materials (concrete, weighted bases) stay put; lighter DIY pieces should still be solid.
• 09Shipping risk: heavy concrete and park pieces need protective packing around corners, not just bubble wrap around the whole obstacle.

A clear obstacle listing reduces buyer questions and post-sale disputes. Include the same core details buyers need to evaluate fit and condition.^{1, 9, 17, 22, 13, 12, 10, 11}

• 01Dimensions: length x width x height, with the unit stated; note if measured rather than from the catalog.
• 02Material: wood (and species if known), plastic, metal, concrete, or mixed.
• 03Rail type: round, flat/square, or angled/kinked, plus rail material and how it is mounted.
• 04Obstacle category: rail, ledge, curb, ramp/quarter/bank/kicker, manual pad, box, or funbox.
• 05Brand and model if known, or clearly state DIY/handmade.
• 06Product line and snapshot context: include sub-line/model details like Blackriver Concrete, CreteDoctor Bird Bath, YEE A-Barrier, Yellowood Mini wall, WhytMyk Mini Ditch, or Harrier, but do not imply current retail price from an old receipt or listing.
• 07Condition: warping, rail straightness, surface wear, concrete chips/cracks, missing rubber feet/stoppers, and any missing hardware.
• 08Shipping: call out heavy concrete weight, corner protection, and whether original packaging or a wooden/product box is included.
• 09Photos: top surface, rail/coping close-up, the obstacle on a flat surface, and any damage.
