Product Advantages

• Suction‑Cup Design: The clear cup sits flush against the underside of the glass shelf; sliding, shifting, and wobble are eliminated completely
• Gentle on Glass: The flexible plastic/silicone head creates a buffer between metal and glass; prevents scratching, chipping, and surface wear over time
• Clean Appearance: The transparent cup stays unobtrusive; the nickel‑plated shank blends discreetly with cabinet interiors for a neat, modern look
• Universal 5 mm Fit: Matches the most widely used hole standard; works with almost all factory‑built and custom‑made cabinetry
• Strong Metal Body: Far more durable than all‑plastic pins — will not snap, crush, or deform under load; stays firmly seated for years
• Quick Installation: No extra tools, screws, or adhesives needed — simply insert into the hole and rest the shelf in place
• Adjustable & Reusable: Change shelf heights whenever you wish; remove and redeploy pins in other projects
• Value Bulk Pack: 500‑count supply delivers low unit cost and simplifies stock management for continuous‑production workshops

Installation & Usage Guidelines

• Confirm hole diameter is exactly 5 mm; select alternative sizes if your holes differ
• Push the pin gently into position; do not force — excessive pressure may enlarge the hole or break the pin
• Make sure the suction surface is clean and dry; dust, grease, or moisture will reduce holding power
• Press the glass shelf down gently once positioned — this activates the suction seal
• Use a minimum of 4 pins per shelf; increase quantity for wider or heavier shelves
• Centre the glass over the pins; uneven weight distribution can cause the glass to crack
• Lift shelves slowly when removing; allow the suction cup to release gradually — sudden pulling may shatter the glass
• Dry the suction head after use in damp environments; prolonged water contact can weaken performance over time

Frequently Asked Questions

Will the suction cup harden or degrade?
Manufactured from premium PVC/silicone, it remains flexible for years under normal use. Lifespan may shorten with prolonged exposure to extreme heat or direct sunlight; periodic inspection is recommended in those locations.

Can it be used on wood shelves too?
Yes — it works effectively on wood and particleboard, where the cup serves as an anti‑slip stabiliser. Plain‑head pins are also an option for solid‑wood installations.

What glass thickness is best suited?
Optimised for 6–8 mm glass. Thicker, heavier glass may exceed single‑pin capacity — increase pin count accordingly.

What if my holes are not 5 mm?
Suction‑cup pins are also available in 6 mm and 8 mm diameters. Measure your holes and select the matching size.

Is there a warranty?
Covered by a 2‑year manufacturer warranty against defects. Unopened items may be returned within 14 days of delivery.
