Open Menu Tel Corners The corners are the second indispensable element for producing the connecting frames for rectangular ductwork. Only optimum interplay between flange and corner allows for the best possible results regarding tightness, stability and ease of assembly.The Gebhardt-Stahl P, S and D corners do this exactly and combine rational processing with stability and tightness. This is where small details make a big difference - from holes for fixing or aligning, burr free production and much more. Every detail serves to achieve maximum stability and a tight fit.Due to the better handling, the use of ring wrenches or socket wrenches is recommended for screwing the duct parts instead of fork wrenches. The following screw sizes are suitable for the screw connection of the ductwork: M8 for 20 flanges, M12 for 30 and 40 flanges.In order to provide maximum flexibility, the corners are available in various designs - e.g. with short leg, with long leg as well as a corners with notch for assembly without punch press. Decide for yourself, which corner fits best your way of working and your project.All P, S and D corners are suitable for duct connection systems Premium, P and S.Suitable corners for L-Flanges can be found in the "L-Flange" section. 20 Corner P 20/3K Art. no.: 302010020 Suitable for flange systems "Premium", "P" & "S" Clearance 32 mm Short leg 63 mm Galvanised steel PU 500 pcs, Pallet 27.000 pcs Enquiry SL 20/3 Art. no.: 302010016 Suitable for flange systems "Premium", "P" & "S" Clearance 32 mm Standard leg 73 mm Galvanised steel PU 500 pcs, Pallet 27.000 pcs Slotted hole Enquiry P 20/3 Art. no.: 302010010 Suitable for flange systems "Premium", "P" & "S" Clearance 32 mm Long leg 73 mm Galvanised steel, Vollwinkel PU 500 pcs, Pallet 27.000 pcs Enquiry SL20/3L Art. no.: 302220016 Suitable for flange systems "Premium", "P" & "S" Clearance 32 mm Long leg 95 mm Galvanised steel PU 500 pcs, Pallet 24.000 pcs Slotted hole Enquiry P 20/3L Art. no.: 302220010 Suitable for flange systems "Premium", "P" & "S" Clearance 32 mm Long leg 95 mm Galvanised steel PU 500 pcs, Pallet 24.000 pcs Enquiry 30 Corner SL 30/3K Art. no.: 302070025 Suitable for flange systems "Premium", "P" & "S" Clearance 32 mm Short leg 73 mm Galvanised steel PU 250 pcs, Palett 12.000 pcs Slotted hole Enquiry SL 30/3 Art. no.: 302070010 Suitable for flange systems "Premium", "P" & "S" Clearance 32 mm Standard leg 103 mm Galvanised steel PU 250 pcs, Palett 12.000 pcs Slotted hole Enquiry SKL 30/3 Art. no.: 302070020 Suitable for flange systems "Premium", "P" & "S" Clearance 32 mm Standard leg 103 mm Galvanised steel PU 250 pcs, Palett 12.000 pcs Small screw hole 9x12mm Enquiry S 30/4 Art. no.: 302050500 Suitable for flange systems "Premium", "P" & "S" Clearance 32 mm Standard leg 103 mm Galvanised steel PU 250 pcs, Palett 12.000 pcs Enquiry 40 Corner P 40/V Art. no.: 302080011 Suitable for flange systems "Premium", "P" & "S" Clearance 32 mm Standard leg 123 mm Galvanised steel PU 150 pcs, Pallet 5.400 pcs Slotted hole Enquiry P 40/4 Art. no.: 302080010 Suitable for flange systems "Premium", "P" & "S" Clearance 32 mm Standard leg 123 mm Galvanised steel PU 150 pcs, Pallet 5.400 pcs Enquiry 20 Corner & 30 Corner with notch P 20/3VH Art. no.: 302010019 Suitable for flange systems "Premium", "P" & "S" Clearance 32 mm Standard leg 73 mm Galvanised steel Slotted hole With notch PU 500 pcs, Pallet 27.000 pcs Enquiry S 30/3H Art. no.: 302550519 Suitable for flange systems "Premium", "P" & "S" Clearance 32 mm Standard leg 103 mm Galvanised steel Slotted hole With notch PU 250 pcs, Pallet 12.000 pcs Enquiry Corner with short clearance D 20/3VK Art. no.: 302020020 Suitable for flange systems "Premium", "P" & "S" Clearance ≤ 5,0 mm Short leg 63 mm Galvanised steel PU 500 pcs, Pallet 27.000 pcs Slotted hole Enquiry D 20/3 Art. no.: 302020010 Suitable for flange systems "Premium", "P" & "S" Clearance ≤ 5,0 mm Standard leg 73 mm Galvanised steel PU 500 pcs, Pallet 27.000 pcs Slotted hole Enquiry SD 30/V Art. no.: 302090010 Suitable for flange systems "Premium", "P" & "S" Clearance ≤ 5,0 mm Standard leg 103 mm Galvanised steel PU 250 pcs, Pallet 12.000 pcs Slotted hole Enquiry SKD 30/V Art. no.: 302090015 Suitable for flange systems "Premium 30", "P30" + "S30" Clearance ≤ 5,0 mm Standard leg 103 mm Slotted hole 9 x 12 mm PU 250 pcs, Pallet 12.000 pcs Galvanised steel Enquiry D 40/V Art. no.: 302080050 Suitable for flange systems "Premium 40", "P40" + "S40" Clearance ≤ 5,0 mm Standard leg 123 mm Slotted hole 13 x 16 mm PU 150 pcs, Pallet 5.400 pcs Galvanised steel Enquiry YOUR CONTACTS Your team “HVAC COMPONENTS” For all queries please don´t hesitate to contact us.
