Structure Fittings – Equal Bracket

Structure Fittings – Equal Bracket

A structure fittings equal bracket (EBT Series) is a right-angle inter-tube junction component used to form rigid orthogonal connections between structural tubes of the same nominal bore in support frameworks for borosilicate glass process equipment. Goel Scientific Glass Works Ltd. manufactures the EBT equal bracket series in robust cast iron (hot-dip galvanised) and 304/316 stainless steel variants, designed to slide smoothly onto matching structural tubes and lock securely via grub screws without welding or hot work.
The equal-leg geometry provides fitters with a symmetric orthogonal junction that transfers lateral and vertical loads evenly across horizontal and vertical members, maintaining frame alignment and preventing twisting stresses.

Key Features

  • Symmetric Equal-Leg Geometry: EBT series equal brackets distribute mechanical loads evenly across both perpendicular tube branches.
  • Tool-Only Modular Assembly: Slides directly over matching tubes and locks via grub screws, enabling rapid assembly, adjustment, or disassembly without welding.
  • Precise Socket Dimensions: Accurate inner socket tolerances ensure full engagement along specified socket depths (h and L), keeping the framework square.
  • Offset & Clearance Control: Engineered L1 clearance dimensions allow optimal frame offset for secondary bracing and equipment mounting.
  • Corrosion-Resistant Options: Standard galvanised cast iron for plant environments, with electropolished SS 304/316 for aggressive atmospheres and cleanrooms.

FAQs

A structure fittings equal bracket is used to connect two structural tubes of the same nominal bore at a right angle, creating rigid horizontal-to-vertical junctions in glass process support frames.

Equal brackets feature precision sockets that slide directly over matching structural tubes. They are locked into position using threaded grub screws, requiring only basic hand tools for installation.

Standard brackets are manufactured from high-durability galvanised cast iron. For cleanroom and highly corrosive environments, Goel Scientific supplies precision-cast SS 304 and SS 316 stainless steel variants.

Yes, EBT brackets are specifically dimensioned to match standard 25mm, 30mm, 40mm, and 50mm Nominal Bore (NB) galvanised and stainless steel structural tubes.

No, equal brackets eliminate the need for welding, cutting, or hot-work permits, making them ideal for safe on-site installation and future framework reconfigurations.
