[ ! ] *2Aluminum Frames, An effective length of 4000 mm means that the frame has an effective length of 4000 mm or more that can actuallybe used.
The actual length including the gripping area is 4000 mm or more (it will be several tens of mm longer).
The fixed-length frame is a frame that is cut by the customer, so the exact length cannot be specified.
[ ! ]Aluminum Frames, A heat resistance temperature of up to 70°C is recommended. Continuous temperatures above 100°C will causebending due to the load.
However, temporary high temperatures such as steam can withstand temperatures up to 100°C.
Alterations of Aluminum Frames (Specified Length Only, Fixed Length Not Possible)
[ ! ]Aluminum Frames, By using the various alterations listed below, MISUMI's specified length aluminum frames allow for greaterflexibility in assembling structures.
Some frames are not applicable depending on the type and size. Please check the price list listed on eachalteration page to see if the alteration is applicable.
Aluminum Frames, Items marked with "-" in the price list are not applicable.

|---|---|---|---|---|
| End face tapping | End face tap (center hole) | LTP/RTP/TPW LHP/RHP/HPW | ![]() | The frame is tapped. LTP/RTP/TPW: M8 depth 24mm LHP/RHP/HPW: M5 depth 10mm (with helical insert inserted) This processing is required for blind joints ( screw joints / simple joints ). |
| Change cutting method | High-precision cutting | SC | ![]() | Aluminum Frames, The tolerance of the overall length L has been changed from L±0.5 to L±0.2, allowing for high-precisioncutting. *Only applicable to L≦1500 |
| 45 degree cut | L□T45 R□T45 | ![]() | The cut is made at a 45-degree angle. 45-degree cuts cannot be specified in the same direction with other alterations. Example: HFS6-3030-500- L TP- LAT45 ⇒ ✖ (alterations in the same direction (left)) HFS6-3030-500- L TP- RAT45 ⇒ 〇 (separate alterations on left and right) [ ! ]If you would like to cut at an angle other than 45 degrees, please contact our catalog non-standard product service . | |
| Wrench Drilling | Fixed position wrench hole | LCH/LCV/LCP RCH/RCV/RCP | ![]() | Aluminum Frames, This additional processing is required to drill a wrench hole (φ7.35) to match the position of the tap onthe end face of the mating frame when fastening a blind joint that assembles frames into an L shape. Blind joints that require this processing ( screw joints / single joints / tapping joints ) |
Hole position shifted by the thickness of the frame cap | FL FR | ![]() | Aluminum Frames, The hole position for the additional fixed position wrench hole is moved by the thickness of the frame cap(2.5 mm). This prevents the frame cap from protruding when assembled at a corner. | |
| Wrench holes at specified positions | AH/BH/CH/DH/EH AV/BV/CV/DV/EV AP/BP/CP/DP/EP | ![]() | Aluminum Frames, This is an additional process to drill wrench holes (φ7.35) at any desired position. It can be used whenfastening blind joints at locations other than the frame end. ・ Up to five holes can be drilled in each of the horizontal, vertical, and cross directions. [!] If you require six or more wrench holes, please contact our non-standard product service . | |
| Counterbore Drilling | Specified position counterbored hole | Z5-XA○○ Z6-YA○○ | ![]() | Aluminum Frames, This is an additional process to drill a counterbore hole (selectable from Z5 or Z6) at any position. ・Z5: Through hole φ5.5, counterbore hole φ9.5, Z6: Through hole φ6.5, counterbore hole φ11 . ・Up to five holes can be drilled in one direction. ・For frames with multiple rows of grooves on one surface, counterbore holes will be machined in allgrooves. [ ! ]If you require more than six counterbore holes or to change the direction of the counterbore holes, please contact our non-standard product service . |
| Drilling holes specifically for blind joints | M hole | LMH/LMV RMH/RMV | ![]() | Drills holes required for connecting post-assembly double joints and center joints. ( Post-assembly double joints / center joints ) |
| Other processing | C-chamfered end | CW | ![]() | The outer periphery of the frame end face is chamfered. |
| Sticking stickers | ZZZ | ![]() | Aluminum Frames, A sticker printed with the catalog number etc. is attached to the aluminum frame. There are restrictions on the number of characters etc., but it is also possible to print the customer'sserial number and unit number. |

■How to think about the allowable guideline load (deflection) for Aluminum Frames
[!]Aluminum Frames, The allowable guideline load is the load that causes the frame to deflect within 1 mm per 1000 mm of length.
Deflection exceeding this will not cause damage, but it should be considered the maximum practical deflection.(The allowable guideline deflection is proportional to the length. For example, 500 mm = 0.5 mm, 2000 mm = 2 mm.)Please refer to
or for your reference.
