The Kapro 317 series adjustable T-line is a tool designed for precise marking and straight cuts in panel, wood and interior construction. The sliding T-head allows free adjustment of the angle, and a clear screw lock keeps the head in the selected position. The solution is particularly suitable for situations where repeated markings are required at the same angles or where the angle needs to be adjusted depending on the object.

The frame is made of aluminum and its double-edged blade is suitable for both measuring and as a ruler for drawing cutting lines. The anodized surface supports the durability and feel of the measuring scale. The bidirectional printed scale (cm/in) makes it easier to work with mixed dimensions and reduces the need for conversion calculations on the job site.

The end features etched angle markings that allow you to quickly find the most common angles without external tools. The groove in the profile allows you to start marking and cutting directly from the edge of the sheet without moving the ruler.

The “hands-free” ledge on the ABS end panels helps keep the T-Liner in place on the edge of the piece without having to press down. This leaves one hand free for a marking pen or cutting knife. The structure folds for transport and storage, saving space and making jobsite transfers easier.

The combination of an adjustable head, screw lock and bidirectional scale makes the tool a versatile solution for both straight 90° marking and drawing inclined lines and repeating angles. The combination supports the general dimensioning and marking needs of drywall, carpentry and interior installation.

Intended use:

Drywall and panel cutting – Measure, mark and draw lines on gypsum, fibreboard and plywood panels directly from the edge of the panel. The sliding T-head and screw lock enable both straight 90° alignment and individually defined angles for example for angled enclosures. The ledge shelf holds the ruler securely on the edge of the panel, making it easier to mark and repeat long cutting lines.
Woodworking and furniture frame marking – Marking out timbers, mouldings and furniture frames requires both vertical and horizontal lines and occasionally angles. Etched angle markings help with repetitive angles, and the bidirectional cm/in scale speeds up work with mixed dimensions. The double-edged blade also acts as a safety ruler when cutting with a knife.
Flooring and Carpeting – Drawing straight cuts and angles on carpets, vinyls and laminates is easy when the ruler rests on the edge of the piece on the ledge. The screw lock ensures that the angle does not change during marking, which improves the cleanliness of the fittings, for example, at thresholds and wall lines.
Electrical, HVAC and ducting – When routing ducts, gutters and cover strips, the ruler marks straight and diagonal lines on enclosures and walls. The profile's groove makes it easy to start marking right next to the edge, and the folding structure moves with you inconspicuously as you move from one object to another.
Interior and Finishing – Alignment of shelves, railings, curtain rails and paneling. The sliding head and etched corner markings help when the wall or ceiling is not perfectly straight and small corner compensations need to be made to smooth the finish.

Features:

Adjustable sliding head: Angle freely adjustable – allows for both 90° markings and bevel cuts without separate angle measurements.
Screw Lock: Locks the head at the desired angle – prevents the angle from changing when marking long lines.
Double-edged, sturdy blade: Works both for measuring and as a ruler – straight, long marking lines and clean cutting directions.
Bidirectional scale (cm/in): Makes reading from both directions easier – reduces the need to convert units of measurement.
Etched angle markings on the tip: Provide quick reference to the most common angles – speeds up repetitive marking.
ABS end-end ledge: Hands-free support against the edge of the piece – the ruler stays in place better during marking.
Profile grooving: Allows marking and cutting to start directly from the edge of the sheet – speeds up work.
Foldable structure: Takes up less space for transport and storage – makes it easier to move around the jobsite.
Aluminum body, anodized surface: Smooth feel and clear scale – comfortable to use for repeated marking.

T?Liner Kapro 317 user manual:

Preparation: Check that the tip moves freely and the screw lock works. Wipe the blade and tip free of dust before use.
Angle setting: Loosen the screw lock, adjust the head to the desired angle (or 90°), and tighten the lock securely.
Marking straight from the edge: Place the ledge on the edge of the piece. Press the ruler lightly in place and draw a line along the double edge.
Marking a diagonal line: Adjust the angle of the T?head. Lock with the screw lock. Draw a line parallel to the blade; make sure the angle does not change during work.
Repeating Markings: Take advantage of etched angle markings and a bidirectional scale for repeating angles and measurements.
Care and storage: Clean with a soft cloth. Avoid solvents that may affect the surface or scale. Fold the frame for storage and avoid placing it under heavy objects.

Warnings:

Avoid placing your fingers between the blade and the workpiece when drawing the line.
Do not use near live wires without proper precautions.
Do not use with damaged or loose locking – check the screw lock regularly.
Keep out of reach of children.

Frequently Asked Questions, FAQ:
How do I prevent the corner from moving during marking?
Tighten the screw lock securely before marking and make sure the contact surface of the T?head is flat against the piece. The ledge helps hold the ruler in place during long lines.

Can I use the ruler with both cm and inch measurements?
Yes. The bidirectional scale includes both centimeter and inch graduations, making it easy to work in mixed measurement environments.

How do I mark a line right from the edge of the board?
Take advantage of the profile's groove: place the T?head on the edge and use the groove to guide the pen or knife right next to the edge.

Is a ruler suitable as a cutting guide?
Yes, the double-edged blade acts as a ruler when cutting with the knife. Use caution and keep your hand away from the cutting line.

Can the ruler be folded for transport?
Yes. The structure folds, making it easy to transport and store.
