50×25mm Rectangle Slotted Bases

Injection-Moulded ABS Plastic · UK Designed · Hobby Heaven

📦 What This Is

50×25mm rectangle wargaming bases with two parallel slots, made from injection-moulded ABS plastic. The classic cavalry and large-infantry footprint for rank-and-file mass-battle systems — the parallel slots run along the length of the base, letting tab-fitted mounted models clip straight in. Black, ready to prime and texture.

🔧 Material & Build

Injection-moulded from ABS plastic — the same family of materials used in LEGO bricks. ABS does not warp, holds its shape over time, and bonds reliably with superglue (cyanoacrylate) and two-part epoxy. The textured top surface grips PVA, texture paste, and basing sand without needing to score or rough up the surface first. Takes all spray and brush-on primers cleanly.

Every mould in the OBS range is designed in-house using industry-standard CAD — these are not generic imports. We control the full production chain from design through to quality control. Mould lines are clean and consistent.

The two parallel slots are 35mm long and 2.35mm wide, set 3mm apart and centred on the base, running along the 50mm length so mounted models face forward in formation. At 3.6mm total height with a 1.4mm floor, this is a slim, rank-friendly profile. The underside has a 2.2mm-deep channel either side of the slots — room for 3×2mm disc magnets, one in each channel for a balanced hold.

✅ Compatibility

50×25mm rectangle (often listed as 25×50mm) is the standard cavalry and large-infantry base format across fantasy and historical rank-and-file wargaming. The slotted version accepts tab-fitted mounted models directly — no trimming required for standard-width tabs.

Each base takes the frontage of one 25mm square infantry base and the depth of two, so cavalry ranks line up cleanly with infantry regiments on the same table. Fits standard movement trays designed for this footprint.

Worth knowing: length is a full 50.00mm, but width measures 24.00mm at the base edge — 1mm under nominal. Units drop into 25mm-pitch movement trays without binding; if you rank these directly against other-brand 25mm-wide bases, ours will sit very slightly narrower.

Part of the Open Basing System (OBS)

One Ecosystem · Every Size · Every Shape

OBS is a modular basing ecosystem designed as a whole — not a random collection of bestsellers. Every size, shape, converter, and tray is planned to work together. Independent and gamer-built.

➜ 50×25mm Plain Bases — same size, no slot — for models without tabs

➜ Other Rectangle Sizes — 60×30mm, 60×40mm, 50×75mm, 50×100mm for heavier cavalry, chariots and war machines

➜ 25mm Square Bases — the matching infantry footprint for the same regiments

➜ Movement Trays — formation blocks for ranked regiments

New products added regularly — the OBS range is always growing.

💡 From the Workbench

PREP

Wash before priming — a quick rinse in warm soapy water removes mould release residue. Dry completely before spraying.

USING THE SLOTS

The two parallel slots are oriented front-to-back so mounted models face forward in formation. Tab-fitted cavalry clips straight in — apply a drop of superglue to the tab before seating for a permanent bond. If a tab is a touch thick for the 2.35mm slot, a couple of passes with a sanding stick on the tab gives a snug fit. For models with a single wide tab, use one slot and fill the other with texture material.

DON'T NEED THE SLOTS?

Fill them with milliput, greenstuff, or a strip of plasticard glued flush. Plasticard sits flat in parallel slots with minimal cleanup — cut to width, CA gel in place, sand smooth once cured. Prime over and the surface is seamless.

MAGNETS

2.2mm underside clearance takes 2mm-thick disc magnets — 3×2mm is the safe choice. Place one in each of the two side channels, either side of the slots, for a balanced hold in transport. CA gel, check polarity before it sets.

RANKING UP

Keep texture and scenic material off the bevel edges — clean edges mean tight formation ranks with no gaps. A uniform rim colour across the regiment ties the unit together visually on the table.
