Pass مربع الباب المفصلي
A robust stainless-steel butt hinge that supports repeated pass box door movement while maintaining stable panel alignment.
- Satin Stainless Construction
- Eight-Point Mounting
- Full-Length Hinge Pin
- Stable Door Alignment
مقدمة المنتج
The pass box door hinge connects the transfer-chamber door leaf to its frame and carries repeated opening loads without introducing excessive play. Two machined stainless leaves, eight countersunk fixing points and a continuous pin distribute load along the joint. The satin surface is suitable for routine wipe-down, while the compact butt-hinge geometry fits flush chamber construction. Replacement selection should match leaf dimensions, hole centers, pin axis, door weight, opening angle and the existing frame reinforcement.
الخصائص الرئيسية
Eight countersunk holes allow flush fastener seating without protruding heads.
A continuous pin maintains a consistent pivot axis through repeated operating cycles.
Satin stainless surfaces resist routine cleaning exposure and match pass box interiors.
مخاوف المنتج للعملاء
A replacement hinge must match the existing pivot line and fixing pattern to prevent sagging, rubbing or loss of gasket compression.
A shifted pivot axis causes the door edge to rub the frame.Leaf width, barrel offset and mounting position are matched to the original hinge centerline.
Insufficient fixing support allows the hinge screws to loosen under door weight.Eight countersunk locations spread the load into suitable frame and door reinforcement.
Pin wear creates door play and inconsistent gasket compression.A close-fitting full-length stainless pin provides a stable bearing axis and replaceable service point.
Rough or corroded hardware is difficult to clean in the transfer area.Smooth satin stainless leaves and barrel provide a durable wipe-clean exposed finish.
