Ușă glisantă din sticlă securizată, model 3D LD 623 made to order

LEBO 3D LD 623 sliding glass door with tempered glass and stainless steel track — seamless opening with acoustic comfort for contemporary interiors.

The LEBO 3D LD 623 sliding glass door redefines spatial flexibility with a refined solution for effortless, reversible zone separation. Positioned in LEBO's modern range, this series merges geometric transparency with German-engineered precision, ideal for open-plan residences or contemporary offices demanding adaptive room division.

Tempered safety glass in 8–10 mm thickness guarantees durability and protection, resisting impact without shattering into dangerous fragments. The stainless steel track system ensures fluid, whisper-quiet operation with integrated front and rear damping that prevents collision damage and extends mechanical lifespan. The minimalist hardware approach—stainless fittings only—preserves glass as the visual focal point, creating an almost invisible door effect where geometry alone commands attention.

Thermal and acoustic performance suits interior applications well, with glass's natural sound-dampening properties reducing ambient noise gently. Horizontal wall-mounted installation offers maximum flexibility—the door retracts fully without occupying traditional swing space. The load-bearing capacity and guiding mechanism are engineered for frequent use without premature wear, with German certification backing reliability and longevity.

The LD 623 adapts seamlessly to any interior palette and aesthetic, as transparent glass remains eternally neutral. Available in two thicknesses—8 mm for standard openings, 10 mm for wider spans and higher traffic—the door allows personalisation through discrete threshold or suspended installation. The sliding system integrates into phased renovations without structural disruption.

Ideal for open-plan living areas, private offices within shared spaces, modern closets, or kitchen boundaries that preserve visual continuity. Pairs beautifully with minimalist finishes—polished concrete, large-format tiles, light timber—and contemporary furnishings. The door functions simultaneously as both practical divider and sculptural element, inviting natural light to model space with understated elegance.

The LD 623 uses VSG/ESG safety glass with a thickness of 8–10 mm, which fragments into harmless pieces upon impact, ensuring maximum protection. The glass passes rigorous strength tests and is not easily broken, making it ideal for high-traffic areas and homes with children.

The door slides on stainless steel rails mounted on the wall or floor, ensuring smooth linear opening without a visible threshold. The system uses high-quality bearings that enable effortless, silent gliding, eliminating friction noise and maintaining consistent performance over time.

The LD 623 provides 26 dB of acoustic insulation, reducing moderate noise and conversations from adjacent spaces, making it suitable for bedrooms and focus areas. For maximum insulation in high-noise zones (near main roads or elevators), we recommend consulting about options with additional laminated glass variants.

The LD 623 sliding door is mounted on stainless steel rails, either on the wall (above the doorway) or on the threshold, with easy horizontal position adjustment. Installation requires straight masonry and perfectly aligned rails; we recommend a qualified technician to ensure linear gliding and proper glass panel balance along its full length.

The LD 623 model is available in standard sizes but can be customized to order to fit non-standard openings and specific spatial requirements. We consult with each client on exact door measurements, width, and height, to create a perfectly tailored solution matching the room's geometry.

Clean the glass with water and neutral detergent on a soft material; avoid abrasives and strong acids that may scratch the surface. Stainless steel rails require regular cleaning with a soft brush to remove dust and debris; occasional application of light silicone lubricant keeps sliding smooth and prevents long-term mechanism jamming.
