Build a compact frame with a clear specification
Choose the right section and matching connections for your assembly. These benefits depend on the frame layout, the selected hardware and the agreed supply details.
Make room for the equipment
Use the nominal 20 × 20 mm family as a compact framing option for small enclosures and supports. Check usable space after allowing for brackets, panels and doors.
Assemble and adjust with matched hardware
Appropriate mechanical connections let you plan a frame that can be assembled, dismantled and adjusted. Confirm access to fasteners and the required joint design.
Resolve fit before parts arrive
Keep the section drawing, hardware details and cut-length list together. Identifying those interfaces before ordering helps reduce wrong-part purchases and assembly rework.

Choose around your application
Start with the space and connections your assembly needs. Review the three compact-frame applications below, then identify the section using its dimensions, loading and support conditions. These layouts do not establish a load rating.
Benchtop instrument support racks
Provide equipment weight, support positions, unsupported spans and any vibration or alignment requirements. Review section properties and joints for the intended assembly.
Tabletop display and panel frames
State the panel size, visible faces, appearance reference and how often the frame needs to be dismantled. Confirm feet, joints and panel fasteners together.
AI-generated application concepts only. These are not completed customer projects, tested assemblies or certified safety enclosures.
Start with the information you have
Send a selected drawing for a new frame, or photos and measurements for a replacement. The guides below help you identify missing details. Use the existing inquiry form or WhatsApp to start; drawings and photos can be shared through the existing contact channels. Processing requirements and commercial terms are reviewed during quotation.
Identify an existing profile without a drawing
For replacement parts or an unlabeled frame, send clear photos and basic measurements to begin identification. Keep a sample where possible; a 2020G name or photo alone does not establish a final match.
Photograph the cut end
Show the whole cross-section square-on, in focus and without an obstructed edge. Include a ruler or other measurement reference and a separate close view of the slot.
Show the sides and current connections
Photograph the longitudinal faces, corners, joints and panel fixings. Include any markings or supplier model label that remains.
Record the outer and groove dimensions
Measure outer width and height, slot opening, internal cavity and depth where accessible. Record the center-bore diameter and relevant wall measurements; mark anything you cannot measure.
Include a mating part or sample
Show the existing nut, bolt and bracket with dimensions or part numbers. Keep the original section and hardware available for comparison where fit is critical.
Photos and measurements support preliminary identification. Confirm the final replacement against an agreed drawing or sample before ordering.
Check the complete hardware interface
Match each connection to the chosen section. The slot-4 version has an M4 square-nut connection reference; the thread designation alone does not establish that any particular nut or bolt will fit.
Nuts: body and thread
Compare nut width, height, body shape and thread with the groove cavity and lips. Confirm whether the nut is inserted from the end or can be installed after the frame is assembled.
Bolts: length and engagement
Check the bracket or panel stack, nut position and bolt length together. Confirm adequate engagement and clearance from the groove base using the component drawings.
Brackets: location and holes
Check the bracket size, locating features, hole spacing and tool access. Confirm any section drilling or end machining before assigning a bracket.
Panels: thickness and fixing
State panel thickness, edge clearances and the fixing method. Coordinate hinges, retainers, seals or covers with the profile and door layout where applicable.
This is a drawing-review checklist, not a tested accessory compatibility list. Confirm named hardware part numbers or a trial fit for the selected assembly.

GB 2020G selection and purchasing questions
What is GB T-Slot 2020G Series used for?
It is a nominal 20 × 20 mm profile family for compact modular frames such as small equipment enclosures, instrument racks and displays. APW supplies the two listed versions. Select the actual section, supports and connection design for your assembly; the family name alone gives no load rating.
Can I start an inquiry without a drawing?
Yes. Send a clear end-on photo, side and connection photos, outer dimensions and accessible groove measurements. Include existing hardware details or a supplier reference if available. These help begin identification; the final section is confirmed against an agreed drawing or sample.
How do I match a profile for an existing frame?
Compare the original and proposed cross-sections, groove cavity, opening, depth, bore and mating hardware. Provide the existing nut or bracket dimensions and describe which parts must remain unchanged. Agree the replacement drawing or sample before ordering.
Does slot 4 mean an exact 4 mm opening?
Slot-series names and measured openings are different specifications. Use the actual opening shown for the selected version in the comparison table and drawing. Do not assign the slot-4 geometry to the light-wall version without checking its own section.
Which hardware details should I confirm before ordering?
Confirm nut body dimensions and insertion method, thread, bolt length and engagement, bracket locating features and hole positions, panel thickness and tool access. The M4 connection reference belongs to the slot-4 version; it is not blanket approval of Euro 2020, V-slot or another manufacturer’s accessories.
What material and surface finish are available?
The listed versions are supplied in 6063-T5 aluminum. Silver anodizing is specified for the slot-4 version. Agree the light-wall version’s surface treatment and appearance reference separately. Identify the selected section and finish together in your inquiry.
What should my quote request include?
Start with the selected version and drawing, or existing-profile identification information. Add a cut-length list with piece counts, finish, tolerances, hardware details, any processing drawing and destination. Use the worked example as a format. Price, processing feasibility, minimum order and delivery terms are confirmed in the quotation.
