Floor Spring for Glass Door: Weight and Opening Guide

Updated: October 29, 2026

A floor spring for glass door projects must be selected against the complete entrance, not a catalog headline. HIPAD’s supplied Door Controls reference lists floor springs for glass and entrance doors up to 150 kg with a 180-degree opening reference. Before approval, confirm the quoted model, door geometry, floor construction and glass fitting interface through drawings and a representative sample.

Published Door Controls reference

The HIPAD source library provides family-level values, not a universal rating for every configuration. Use the comparison below to frame a supplier inquiry.

A floor spring, pivot and closer do not become interchangeable because their opening references overlap. Compare function and installation in the HIPAD Door Controls range. The product reference does not disclose a certificate number, model-level load table or a single fitting geometry for all floor springs.

Door mass is only one input

Send the supplier the leaf height, width, thickness, glazing build-up, measured mass and intended pivot position. A wide leaf can change forces on the controls even if its mass falls below the family maximum. Request the quoted floor spring’s application range, fixing layout and complete matching hardware schedule. Do not convert “up to 150 kg” into a guarantee for an unspecified door.

For a replacement installation, measure the existing recess, spindle position, floor finish height and upper support alignment. A replacement with a similar headline capacity may still place the glass in the wrong closed position. If the layout is a pivot entrance instead, the pivot door system guide sets out the distinct structural checks.

Check the floor before choosing the model

Ask the project engineer to identify the structural substrate, recess depth, finished floor build-up, waterproofing and permissible fixing zones. The supplier’s installation drawing must match those conditions. A shallow floor or concealed service route can rule out an otherwise suitable-looking unit. The supplied reference does not provide a universal anchor schedule, so do not improvise one from a product photograph.

Coordinate floor and head support axes in the same drawing set. Check access for adjustment and future service without assuming every model has the same adjustment features. Record any project-specific fire, accessibility or safety requirement and obtain evidence for the exact offered assembly.

Opening angle and glass fitting interface

A published 180-degree opening reference is not a promise that an installed glass leaf can reach that angle. Adjacent walls, handles, stops, seals and pivot offset may limit travel. Build a production-intent sample, measure the usable angle and verify that the glass does not contact nearby construction through its swing.

HIPAD lists stainless-steel patch fittings, but the supplied reference gives no universal glass-thickness or numerical load rating for that family. Request the fitting drawing and glass preparation requirements. Check the patch fitting, floor spring and upper support as a coordinated set. The door-closer guide explains why weight and opening ranges alone cannot settle an assembly decision.

Five-step OEM sample approval

1. Provide door and entrance drawings with dimensions, mass, glazing, opening direction and floor/head sections.
2. Ask for the exact floor-spring model, declared application limits, installation drawing and relevant test evidence.
3. Compare recess, fixing zones, spindle position, finished-floor height and patch-fitting geometry against the building and glass drawings.
4. Install a representative sample; measure clear opening and closing behavior, and inspect alignment and interference across the full travel.
5. Freeze the approved drawings, material and finish, inspection points, packaging and replacement-part plan before repeat ordering.

EN 1154 addresses controlled door closing devices and is useful terminology when discussing evidence. It is not proof that a particular HIPAD floor spring is certified. Ask for model-specific reports if the project requires conformity. Prices and product-level certificate numbers are not disclosed in the supplied material; request a quote for the specified model and quantity.

FAQ

Can any 150 kg glass door use this floor spring family?

No. The published value is a family reference. Door geometry, model conditions, floor support and matching fittings still need approval.

Does the 180-degree reference guarantee a full 180-degree installed swing?

No. The available angle depends on pivot position and surrounding construction. Measure it on the representative entrance.

Can a patch fitting be chosen after the glass is drilled?

That is risky. Obtain the exact fitting drawing and glass preparation before fabrication, then check its compatibility with the chosen control.

What if the floor recess is too shallow?

Raise the constraint before selecting the model. The supplier and project engineer must verify a compatible installation; do not alter structural details from a generic diagram.

For an OEM sample or model-specific quotation, send HIPAD the door schedule, floor/head details and glass preparation requirements. The next approval point is the complete assembled entrance, not the family headline rating. The supplier checklist can help document drawing and inspection control.
