Square × rail
Which guide rail square variant fits?
GRS-16 variants are rail-profile specific. Select the exact suffix and rail system instead of treating the square family as universal.
Check the exact accessory and rail
Selections stay in this browser and are not stored or sent. RailMatch never asks for an account, serial number, purchase history, image, location, or free-text project description. UNKNOWN means the pinned source set does not document the exact combination.
Why the suffix matters
The PE v2, PE D, PE K and PE R rows cover different rail systems. A supported brand on one variant is not evidence for another variant.
Square-to-rail fit is not saw clearance
TSO's GRS-16 PE v2 specification excludes HK 55 saws even though Festool rails appear in its rail list. Use the combined saw, rail and accessory check to keep this exception in scope.
