The P8-4080 aluminum proflie measures 40mm*80mm with 8.2mm T-slot and 2 mounting holes. This profile slotted on all four sides for assembly with other profiles or accessaries: each 40 mm surface has one T-slot and each 80 mm surface has two.
The P8-4080 profileame, like P8-4040 and 4060 profiles, is one of the commonly used profiles, it features high tensile strength and yield strength, making it suitable for aluminum profile frame requiring high structural performance.
